Welcome to the craggy coast of Ireland. The lady rowing her currach into the surf is Maude Delap. She’s a scientist collecting specimens.

And with that introduction, we’re headed out to sea with Maude to collect compass jellyfish. Why? Because no one has ever watched a jellyfish go through a complete lifecycle. So Maude intends to raise one in captivity. Sounds easy: fill a tank with sea water and watch. But the water has to be freshened frequently, and then there’s the issue of feeding the jellies – what do they even eat?

What I like about this book: So much! Starting with the end pages, which show the life cycle of a jellyfish. Then there's the title with marvelous alliteration: mesmerizing medusas. I like the journal headings, like on the first page where it says June 21, 1899 ~ Day 1. And the almost-last page where it says July 8, 1900 ~ Day 383. I love the language of the jellyfish observations: Pump, sway. Pump, sway. I admire Maude’s determination and dedication. And there is back matter! Author Michelle Cusolito includes additional information about jellyfish and Maude Delap, plus an author’s note about how she came to write this book. Illustrator, Ellen Rooney pens her own notes about the research she did to inform her artwork – including a trip to the New England Aquarium in Boston so she could watch (and sketch) jellyfish swimming. 

I had so much fun reading about the jellies that I just had to ask Michelle one question.

Me: How did you come to land on the journal style for your book?

Michelle: This book went through many iterations with varied approaches. Landing on the voice and structure took a long time. From April of 2020 until February of 2021, there were no headings like you see in the final book. Then, in February of 2021, I started trying out headings to help emphasize the passage of time. My initial headings were JUNE, THE NEXT DAY, SIX DAYS LATER, NINE AND A HALF MONTHS LATER, etc. They weren’t quite working, but I didn’t have a solution yet.

And then there was a large gap until I was able to get back to the manuscript. I got the news that I’d be going to sea with Woods Hole Oceanographic Institution. I had to prepare for two weeks of quarantine (in April of 2021—still during Covid) followed by our time on the ship, so all of my attention turned to prepping for the voyage and researching for the book I would write for middle schoolers about the expedition. I was gone for five and a half weeks. When I returned, I needed to actually write that book, so Maude still had to wait.  I didn’t return to Maude’s story until 11 months later, in January of 2022. By then, I had submitted the manuscript for A Window into the Ocean Twilight Zone: Twenty-Four Days of Science at Sea to my editor, so I had time to spend with Maude.

I added the journal style headings on March 4, 2022. I don't recall the exact moment when I thought to add them, but I'm certain my work on A Window into the Ocean Twilight Zone impacted my thinking. That book documents our time at sea and uses the same kind of headings. I’m sure that made the idea click for me.

Here’s something that might be helpful to other writers: Some of my headings in that March 4, 2022 version looked like this:  April 3-4, 1900 (Day XX). I didn’t want to derail my revision process by stopping to calculate the days, so I simply put XX to remind myself to do it later. I use this strategy often when I don’t have an exact number or fact I need, but I don’t want to stop to research or calculate. I know that uses a different part of my brain and getting back to the creative writing brain takes too long.

Thank you, Michelle, for sharing that bit of wisdom for us! Michelle is a member of #STEAMTeam2025. You can find out more about her at her website,  www.michellecusolito.com You’ll find reviews of her other books right here on the blog – just put her name into the search bar on the right.

Beyond the Books:

Find some jellyfish to watch. Ideally, you could watch some at an aquarium, but if you can’t travel to one, check out these videos at National Geographic and the Monterey Bay Aquarium.

Illustrator Ellen Rooney says that sketching is a great way to study nature. “Once you draw something, you understand it in a new way…” whether it’s a jellyfish at an aquarium or a bird outside your window. So grab some paper and pencils and do some sketching. 

Make some jellyfish crafts – you’ll find plenty of ideas here, including how to create a jellyfish costume!
