Kitchen Science ~ Spin Art!

 Our library's Summer Reading theme was "color your world" and one of the activities that kids could do was create spin art. It's fun and all you need are a few things: some cardstock, washable tempera paint, and a salad spinner (NOT the one you use to spin your lettuce!)

 

 Put your cardstock in the basket inside the spinner and squirt some tempera paint on it. You might have to experiment to get it thin enough to move when the spinner spins. 

 

 

Then start the spinner. I discovered that I had to keep pumping the thing to get the paint to push out to the sides (the effect of centrifugal force)

 

You may want to add more drips and drabs of paint to fill in a few blank spaces...

 

 

 

... and then finish off with a white or silver gel pen! Have fun! Oh, and if your salad spinner has holes on the bottom of the outer plastic bowl, make sure to cover your table with a piece of plastic so you don't get paint all over it. Or just do it outside on an old stump.

 

Explore Outdoors ~ Make your own (very quiet) Fourth of July Explosions!

 With the Fourth of July just a couple days away, I thought I'd share some alternatives to fireworks. These hands-on activities will provide plenty of pop, sizzle, and fizz without the big noise.

Chances are you have many of the ingredients in your cupboards, but check the materials lists in case you need to stock up before Friday. Then, after the parade and potato salad, invite friends and family to create their own Fourth of July celebration in your back yard.

Exploding paint Bags ~ more pop than boom!

Blobs in a Bottle ~ a simple take on lava lamps. All you need is oil, water, food coloring - and some alka-selzer.

Erupting Rainbow ~ Of course vinegar is involved!

Fizzy sidewalk chalk fireworks ~ pffff!

For more activities, check out this post from a few years ago

I'm taking a summer break to explore nature in my neighborhood, and catch up on some writing. And of course, I'm tucking a bunch of books in my beach tote for summer reading! 

Enjoy! See you in August!

Plant some Flowers for Your Pollinators!

 

My Pollinator Garden: How I Plant for Bees, Butterflies, Beetles, and More (Books for a Better Earth) 

by Jordan Zwetchkenbaum; illus. by Kate Cosgrove 

40 pages; ages 3-6 

‎Holiday House, 2025

theme: garden, pollinators, ecology

My garden is full of flowers. I like the pretty colors. I like that they smell good.

Those lovely flower smells attract animals that take pollen from one plant to another, so the flowers can make seeds. And those animals, from bees to birds, butterflies to bats, are called pollinators.  Spread by spread readers learn how flowers attract pollinators and how different pollinators carry the pollen. At the same time, we are introduced to a diversity of native bees, butterflies, moths, hummingbirds and bats, flies, beetles, and wasps.

What I like about this book: It’s fun to look at the different pollinators and flowers on each page. There are short-tongued bees and long-tongued bees. Some bees shake the flowers to release the pollen. There’s a fun fact about each of the featured pollinators: what colors they see; whether they fly during the day or night; what attracts them to a particular flower. Back matter includes and author’s note, how to plant for pollinators, a short glossary, sources, and an index to pollinators and their plants.

Beyond the Books: 

Plant some pollinator flowers that are native to your region. You can find a list of plants for your region here at XERCES. If you don’t have a large space for a pollinator garden, plant a way station. A way station flower spot could be as big as the area inside a hula hoop or a few pots on the balcony.

Make sure to have a watering spot for your pollinators. I use a shallow dish with rocks in it. The rocks serve as landing islands once I pour in water. Make sure you keep it filled, especially on hot and sunny days.

Very Bouncy Science - and History

 

Bounce! A Scientific History of Rubber 

by Sarah Albee; illus. by Eileen Ryan Ewen 

48 pages; ages 6-9

‎Charlesbridge, 2024

themes: rubber, science, invention

 It can bounce, bounce, bounce!

Rubber has been around for thousands of years, and chances are that you’ve got some in your dresser drawer or maybe even your pocket. Where that rubber came from, what makes it so stretchy, and how it’s been used throughout history is the meat of this book.

What I like about this book: Sarah begins with how Indigenous people living near rainforests in Mexico and Central America created and used rubber. 

She explains how European explorers took rubber back with them – along with the gold and riches they stole – and how rubber became part of our lives. Sprinkled throughout are spreads labeled “The Science” where she explains bounce, polymer chains, and why pure rubber fails in heat and cold.

I also like the illustrations – they add a touch of fun to this bouncy history. And there is Back Matter! Sarah discusses names of the Indigenous people, and shares some of the troubling details about the sometimes violent history of the rubber industry and some of the environmental issues. She also includes a timeline of the last 3,500 years of rubber history.

Bouncy Science Beyond the Books: 

Compare bounciness of a variety of balls. You’ll need a hard surface for your bounce test and a way to measure height - you can tape a couple yard-sticks or tape measure against a fence, wall, or tree. Drop each kind of ball from as high as you can reach and write down how high it bounces.

Measure stretchiness of a rubber band. First, measure the width (how “fat” the rubber band is) and the loop-length (how long it is before you stretch it). Now hook one end of the rubber band over the end of a ruler and gently stretch the rubber band. How far can you go? If you’re outside, you can let go and see how far your rubber band flies. Try different rubber bands – and remember to pick them up when you’re finished.

Make your own rubber from plants in your yard. Caution: don’t do this if you are allergic to latex! Break open the stem of a milkweed or dandelion and collect the latex in a spoon. Cover the end of your finger with the sap, all the way to the first knuckle-bend and let the sap dry. After 10 to 15 minutes, roll the dried sap off your finger. It will make a slightly stretchy band. To make a “rubber” ball, put a half a teaspoon of sap into 1/4 cup of water and stir with a straw. Slowly add a little bit of vinegar. The acid in the vinegar will make the latex stick to the straw. Gather the latex into a ball, squeeze out the water, and give it a bounce.

Small Science Expeditions

The Observologist: A Handbook for Mounting Very Small Scientific Expeditions 

by Giselle Clarkson 
120 pages; ages 8-13
Gecko Press (Lerner), 2024

“An observologist is someone who makes scientific expeditions every day, albeit very small ones.” With that introduction you know this will be the perfect book to inspire a backyard study of small things: earthworms, caterpillars, fungi, slug eggs…. 

There are only two things you need to know if you’re going to be an observologist:

1. You’ll spend a lot of time looking at the ground (which is closer to you if you’re between the ages of 8-13 than if you’re an adult).
2. You need to be curious. Because being an observologist is like being a detective… looking for clues that lead to something cool and interesting.

After introducing the whats, hows, and whys of Observology the remainder of the book presents four potential expedition sites – and the sorts of things one might study/observe/examine while there. These are places accessible to any kid: a damp corner (perfect site for discovering more about centipedes and fungi); pavement (great habitat for ants and worms); weedy patches (insects galore!); and around the house.

What I like love about this book: I love the introductory section where Giselle Clarkson lays out such things as “principles of observology,” the reasons for scientific names, and the importance of drawing what you discover. I love the table of contents that exudes the feeling of being a field guide to adventure. Each section – er, expedition site – includes one to three spreads filled with details about the organisms one might discover. There’s even a spread devoted to “aural observology” for those who want to recognize insects by the sounds they make. 

“Not all buzzes are alike,” Giselle writes, “and you have to have very clever ears.”

For those using this book as a text, there is a final exam and a certificate at the back – plus a great index for quick reference to the organisms. Best of all, this book is suitable for parents, teachers, homeschoolers, grandparents, and scientifically minded extraterrestrials desiring to learn more about this planet.

Books celebrating Ants and Doves!

Upon returning from my end-of-summer break, I discovered a bunch of summer releases I’d neglected to share. Taking care of that forthwith! Today’s books celebrate animals, behavior, and human interactions.

Rosemary Mosco writes and illustrates a variety of things, from her Bird and Moon comics to chapter books. Her most recent picture book was released in July. It’s about ants – and I love it! 

There Are No Ants in This Book 
by Rosemary Mosco; illustrated by Anna Pirolli 
40 pages; ages 4-8
Tundra Books, 2024  

  
What a nice-looking book this is! It’s the perfect place for… a picnic.

The reason? There are no ants… it even says so on the cover. Except, as we turn the page we discover that there’s one ant. That might be okay, but then two more ants show up, then more until there are Ten Ants! And that turns out to be fine with the character, because she’s discovering just how cool ants are.

What I like love about this book: I love that each ant is a different species, from a tiny acorn ant to a huge dinosaur ant. The back matter provides a brief bio for each of the ten ants, with their scientific name, where they live, and a cool fact. I’d write more, but I want to go check the acorns in the yard for … ants!

Over the past decade or so I’ve enjoyed reading books written by Sara Levine. Whether it’s animal bones or flower talk or math, she combines fun with STEM. Her newest picture book is all about… well, the title says it all.

A Terrible Place for a Nest 
by Sara Levine; illustrated by Erika Meza 
40 pages; ages 4-8
Roaring Brook Press, 2024 

  
When Juno and his mom lost their home, they had to move to a new place.

Juno doesn’t like his new room. The local grocer doesn’t carry his favorite cereal. Making new friends is hard, and mourning doves are building a nest on the fence right next to the gate. “This is a terrible place!” Juno yells. 

What I like about this book: I like how Juno helps the doves when their nest falls to the ground, and how he decides to take them under his wing (so to speak). As the dove family grows, we see Juno’s circle of friends grow, and the ways they come up with to protect the nest, despite its suboptimal location. I also like how Sara’s story focused on a bird that is distributed across the continental US, Mexico, and southern Canada. So any kid reading or listening to this story can see mourning doves – or their rock dove “pigeon” cousins – around their neighborhood.

Beyond the Books:

Make a picnic for the ants in your yard or at a park. What sort of food will you provide? Remember, some ants like sweets, others like meat, and some will eat anything. Make sure you put your ant picnic on a sheet of paper so the ants can reach their favorite food.

Once you’ve made your ant picnic, observe the ants that visit. What ants arrive first? Do they stick around and eat or do they scurry away, only to return with a friend or two or ten? How many kinds of ants did you see?

Maybe you’d rather make a picnic for mourning doves. They like to eat sunflower seeds, millet, oats, unshelled peanuts, and cracked corn. You can learn more about attracting mourning doves at exploring birds.

This summer a robin tried building a nest over a door. It was a terrible place for a nest! Are there any birds nesting in “terrible places” around your house? What kind of bird, and where did they try to build their nest?

More books for Nature Exploration

Last week I featured a couple books for curious young naturalists. This week I've got two more.

theme: plants, animals, observation

Nature Spy Guide 

Words & photos by Shelley Rotner 

32 pages; ages 4-8

 Millbrook Press, 2024

Anyone can be a nature SPY. Here’s how. First you have to GO OUTSIDE.

Because, being a nature spy means you’ve got to see, smell, touch, and hear things close-up and in-person. In this book, Shelley Rotner asks readers to look up, look down, look all around. To breathe in the air and smell the flowers. Look closer, she says. Use your ears.

What I like about this book: Shelley uses simple text and photos of kids in nature to introduce basic observation skills. She reminds nature spies to use all their senses, to observe things both near and far, and most of all, to not give up – because some animals like to hide. I like the back matter, too. She includes a simple plant and animal identification list for things most kids in North America might see. And – even more important for parents looking for ways to incorporate nature spying into daily life – she provides a dozen activities. My fave is “deer ears” with cloud-watching coming in a fast second.

Backyard Bugs (Shine-A-Light) 

by Carron Brown; illustrated by Wesley Robins 

36 pages; ages 4-8

Kane/Miller Book Publishers, 2023    

Did you know you can find amazing animals close to home? Just step outside…

Yay! another book that invites children to head outdoors to discover nature around them. In this case, bugs. From lady bugs to painted ladies, dragonflies to fireflies, this book celebrates arthropods – and a couple of their non-arthropod neighbors.

Beyond the Books: Go outside this week and be a Nature SPY! 

• Look. Listen. Touch. Smell. 
• Draw pictures of what you see. 
• Write notes in your Official Nature Spy Notebook. (If you don’t have an ONSN, they you can make one by folding paper and stapling or sewing it into a notebook.)
• Watch clouds. 
• Watch squirrel antics. 
• Follow ant and snail trails. 
• Smell the roses. 
• Feel the shade on your face. 
• Listen to what the birds and bugs are saying. 
• Use your imagination. 
• And have fun spying on the critters living around you.

Two Books for Exploring Summer

Greystone Kids has a couple books that are perfect for young nature explorers. 

Themes: fungi, nature, hands-on activities

Mushrooms Know: Wisdom From Our Friends the Fungi 

by Kallie George; illus. by Sara Gillingham 

40 pages; ages 4-8

‎Greystone Kids, 2024   

Mushrooms always wear their thinking caps. They know so many things.

For example, they know that there is more beneath the surface than what you see. That being unique is awesome. And that small can be mighty. They also know that it’s important to take care of your neighborhood, your friends, and yourself. Most of all, they know how important it is to stay connected.

What I like about this book: This is a wonderful book on so many levels. There’s the simple text about what mushrooms know, that ranges from ecological understanding to SEL. Sidebars provide another layer that dives deeper into the science of mushrooms. That’s where you’ll find cool info about how fungi send messages to plants, how they glow in the dark, and where you might find them growing. I also love the cute expressions on the mushroom caps. Plus there is back matter! That’s where you’ll find even more information about what mushrooms are, how they’re used to clean up oil spills, and the cool way bird’s nest mushrooms use raindrops to spread spores.

Be a Nature Explorer!: Outdoor Activities and Adventures 

by Peter Wohlleben; illus. by Belle Wuthrich & translated by Jane Billinghurst  

100 pages; ages 6-10

Greystone Kids, 2024 

This book is filled with 52 activities for the curious young naturalist. Peter Wohlleben invites kids to explore what’s outside around them. Record the plants and animals in your own nature notebook, he tells readers – that way you’ll have a book filled with your own discoveries. In addition to taking a pencil and notebook, he suggests a few other things to take along on your outdoors adventures: plastic containers to collect things for further study, a hand lens or magnifying glass, binoculars for observing animals and birds without bothering them, a cell phone to take photos – and maybe a nature app to help identify plants, insects, and other cool discoveries.

The activities are listed in a table of contents, in no particular order. The idea, Peter says, is to browse through and find something that interests you. They range from listening to a tree talk, to following slugs and snails, to mapping plants that move. It’s a great way to beat the “nothing to do” blahs of late summer

Beyond the Books:

Go on a fungus foray. Late summer and into the fall is the perfect time to look for mushrooms and other fungi. Draw what you see – feel free to give them faces, even entire personalities. What wisdom do they have for you?

You’ll find 30+ activities to explore fungi in my book, Funky Fungi: 30 Activities for Exploring Molds, Mushrooms, Lichens & More (co-authored with Alisha Gabriel). Plus there’s more over at Patricia Newman’s LitLinks.

Label some pages in your nature notebook and start some lists of all the birds, trees, wildflowers, insects, and mammals you see in your neighborhood. Share with a friend and ask what they have discovered in their neighborhood. Hint: the more you look, the more you’ll see.

The Ants are Marching...

 Today’s books are all about ants – because I have an abiding fondness for these truly marvelous tiny critters. I once spent an entire month trading barley seeds with harvester ants.

Theme: ants, animal behavior, ecology

City of Leafcutter Ants: A Sustainable Society of Millions 

by Amy Hevron 

40 pages; ages 4-8

Neal Porter Books/ Holiday House, 2024   

Below the towering trees of the dense rainforest canopy of Central America, a population the size of New York City bustles.

It is a city of leafcutter ants, and each one of them has a job to help their city thrive. There are ants that manage the city’s trash, ants that care for the youngsters, and ants that build and tunnel and dig. There are ants that gather food from the forest, ants that grow food in the city, and ants that make medicines to keep everyone healthy.

What I like about this book: I like the way this book takes readers right inside the ant city. I like the bright, bold illustrations. And I like that there’s back matter in which Amy Hevron tells more about Leafcutter ants and the important jobs ants hold in their city. 

The Wonderful Wisdom of Ants 

by Philip Bunting 

32 pages; ages 4-8

‎Crown Books for Young Readers, 2024

Hey! This is an ant. And this is an ant. And this is an ant…

In fact, there is an entire page introducing ants, about ten quadrillion of them (though not all of them individually). In this book you’ll discover things ants love and things they don’t love (such as big feet coming down on top of them!). There’s an introduction to a generic ant colony and the different jobs ants do, how they talk to each other, and a lot about what ants (and people) can do to make the world a better place.

What I like about this book: I like the stylized illustrations of ants and the humor that results from the combined text and illustrations. And the scene where ants discover sprinkles – who doesn’t love sprinkles!

Beyond the Books:

Back in April I interviewed Amy for the Fourth Annual Arthropod Roundtable over on the GROG blog. You can read it here.

Follow some ants. Where are they going? Where are they coming from? Are they carrying anything, such as dead insects or seeds? These are some of the questions that inspired Amy Hevron to write City of Leafcutter Ants!

Create art inspired by ant-watching. Perhaps your questions will inspire a poem or story. Or you might paint a picture of the ants in your neighborhood. Or perhaps you’ll map out where the ants live and work…

You can find more ant activities in one of my earlier blog posts here.

For Plants It's All About The Soil

 

 The Soil in Jackie’s Garden
by Peggy Thomas; illus. by Neely Daggett
32 pages; ages 5-8
‎Feeding Minds Press, 2024

theme: gardening, compost, pollinators

This is the soil in Jackie’s garden.

For those of us who garden, everything begins with the soil. And so it is with this book. Even before seeds can grow, we have soil. And worms. In this cumulative story, Jackie and her friends sow seeds, nurture plants, harvest fruit, and recycle scraps in the compost bin to ensure that the cycle of growth continues.  

What I like about this book: With it’s “house that Jack built” structure, this story is fun to read and will have kids repeating some lines before long. In addition to the story, Peggy Thomas tucks extra information into text boxes: explanations of xylem and phloem, a closer look at root tips and leaves, how plants breathe. Readers will see the garden through seasons of growth, ripening, and harvest. And then there are the close-ups of compost critters – one of my favorite spreads. Back matter contains more information about the soil cycle. 

While I love books that include the occasional vertical spread, I found that having an entire book open that way was difficult for me to hold on my lap. But if you’ve got kids who lay on their tummies to look at books, this format makes perfect sense!

Beyond the Books:

Watch how a seed grows. You’ll need bean or pumpkin seeds, a clear glass jar or plastic cup, paper towels, and an old t-shirt. You can find instructions under “Watch pumpkin seeds sprout” at Patricia Newman’s lit links.

Make some compost. But if you don’t have room to build a compost pile in your yard, you can make compost in a plastic soda bottle. Here’s how. When I did it I used newspapers, banana peels, apple cores, orange peels, egg shells, carrot peelings, and dried leaves.

Plant a bucket garden for pollinators. I use five-gallon buckets, but you can use smaller containers – even a plastic waste basket will work. You’ll need to drill some holes in the bottom for drainage and fill with potting soil. Here’s how to create a $5 bee garden.

Arthropods and the People who Love Them!

 It’s Groundhog Day – and that means that we are Halfway To Spring! Soon there will be snowfleas hopping about, and sap moths – I can’t wait. But for now, while snow and ice make bug life hard, I’m sharing a couple of fun books. You get a two-fer today because my book basket is filling up faster than I can post reviews…

themes: nature, insects, arthropods

Is this a House for a Hermit Crab?

By Megan McDonald; illus. by Katherine Tillotson

40 pages; ages 4-8

‎ Neal Porter Books, 2024 (originally published 1990)

I became acquainted with hermit crabs while doing field research on Cocos Island, Costa Rica. I loved watching them toddle across the beach, carrying snail shells on their back. So when I had kids, of course I read them this book. Now, re-visioned with new artwork, it is just as fun to read as it was more than 30 years ago.

Hermit Crab was growing too big for the house on his back.

So up, onto the shore he climbs as he sets out to find a new house. Something that will give him room to grow and keep him safe from his enemies – especially the porcupine fish. Hermit Crab tries one improbable thing after another – a rock, a tin can… but before he can complete his quest, a wave washes him back into the sea where a hungry porcupine fish lurks!

What I like about this book: The language! Megan McDonald indulges our senses with words that evoke the sounds of the crab scuttling along the beach. Scritch-scratch, scritch-scratch. Then there’s the repetition of this line every time Crab sets off to find a new home: he stepped along the shore, by the sea, in the sand. And there is back matter. Megan explains more about hermit crabs and includes fun facts, such as how many legs they have and how they are best friends with sea anemones. And – whew! Hermit Crab manages to find a home in the nick of time so he doesn’t become a fish meal.

If you read my blog much, you know I am passionate about bugs! So I was eager to get my tarsi on this new-to-the-States book!

The Girl who Loves Bugs

By Lily Murray; illus. by Jenny Løvlie

32 pages; ages 4-8

‎Peachtree, 2024  

 Evie loves bugs! Fat bug and thin bugs and bugs that can fly, beautiful butterflies filling the sky.

She loves bugs SO much that she brings them inside. And then they … escape! On the day Great Gran and the family are coming to visit. What happens when they sit down for a big meal and find bugs on the plates and chairs? But ... instead of being sent to her room, Evie learns that Great Gran loves bugs, too. Together they come up with a marvelous solution for Evie’s desire to care for her mini-beasts.

What I like about this book: What a fun story for kids – and inspired by a real entomologist: Evelyn Cheesman. I like the way we discover that "loving bugs" is fine, as long as they are loved and admired in their own habitat (which is where they feel safest). I love the endpages filled with fanciful insects. And there is back matter! Lilly Murray tells us a bit more about Evelyn Cheesman and shares two fun buggy activities

Beyond the Books:

Some hermit crabs line up to trade shells with their friends. Here’s a video showing how hermit crabs switch shells. And some hermit crabs don’t even bother with shells. They use plastic bottle caps and other trash. You can find out more here.

Pretend you are a hermit crab seeking a safe place to snuggle. What sorts of things might you choose for your home? A sleeping bag roll? A large pillow? A cardboard box? Try it on for size…

Make a Bug Hotel for the beetles and other insects hanging out in your yard. Bug hotels can be pretty simple. Begin with a wooden frame (a CD crate works well) and fill with bundles of sticks, pine cones, leaves, moss, and lichens. This article from University of Vermont can help you get started.

Mole Day!

 

Mole and Tell (Celebrating Science)
by Catherine Payne and John Payne; illus. by Elisa Rocchi
40 pages; ages 7-10
Science, Naturally!, 2023

What’s that date written on the board?

When the students file into Mr. Cantello’s fourth-grade science class, they notice a date written on the board: 10/23. What does it mean? Is it a field trip? A test? Maybe it’s Earth Day? Not Earth Day, Mr. Cantello says, but it is a science holiday. It’s Mole Day, October 23.

Is this a day to celebrate spots on our skin? To celebrate tiny animals that tunnel underground? Nope. It’s a celebration of a number. Avogadro’s number, to be exact: 6.02 x 10²³. It’s a counting unit used by scientists all around the world. Sort of like a dozen, but instead of 12, a mole is 602 billion trillion. That’s 602 followed by 21 zeroes! Scientists write it as 6.02 x 10 to the 23rd because seriously, writing 602,000,000,000,000,000,000,000 every time you need to use it takes up too much space!

What I like about this book: I think the authors do a good job introducing the concept of a mole. And having a group of kids explore what a mole of something is might encourage readers to wonder. There’s some discussion of elements, and an illustration that shows the periodical table along with molar mass (the number of grams in a mole of an element), plus a discussion about the kinds of scientists who use moles to measure things in their jobs. I do wish there had been a sidebar explaining more about who Avogadro was and how he (and others) developed this measurement.

 

I wanted to know more about how Cathy and John decided to write this book, so I asked Cathy One Question:

 

Me: What inspired you to write about such a big number?

Cathy: I've been fascinated by the mole since learning about it in my high school chemistry class. In addition, I love homonyms! This book was the perfect way to combine my love of language with my interest in science. For this book, we focused on breaking down scientific concepts, explaining the mole and the periodic table as best we could. We wanted children to have a solid understanding of the mole so that they would have a good foundation for units of measurement.

There isn’t any back matter beyond a glossary, but Science Naturally provides an activity-filled teacher’s guide at their website. I’ve added a few more activities below at…

… Beyond the Books:

How much would a mole of avocados weigh? Cathy admits she likes to play with language, so why not? Since 6.02 x 10²³  is Avogadro’s number, why not play around with avocados? You can even weigh one (or more) right there in the produce aisle.

Mole Day is next Monday. What kind of food will you make to celebrate? Here’s a couple of ideas to get you started: guaca-mole, pie a’la mole, ani-mole crackers.

Go play a game of whack-a-mole. If you can’t find one (because it IS an ancient and venerable arcade game) try making your own out of cardboard. Here’s how.

Make up your own Science Holiday. What science thing do you want to celebrate? 

Thanks for dropping by today. On Monday we'll be hanging out at Marvelous Middle Grade Monday with other  bloggers. It's over at Greg Pattridge's blog, Always in the Middle, so hop over to see what other people are reading. Review copy provided by the authors.
