Cover Reveal: THE OCEAN’S HEART: The Tiny Creatures Essential to Life

Hip hip hooray!!! Time to lift the curtain and REVEAL a beautiful new picture book COVER!

And this one is for a dear friend, author Jilanne Hoffman who has a new book launching March 3, 2026 from Millbrook Press, illustrated by the amazing Khoa Le.

TA-DA!!!

There is so much we don’t know about the oceans…and just look at this cover!!!! It hints at the mysteries that still are yet to be explored.
And we are so lucky because Jilanne stopped by to share a little bit about the book and why she wrote it.
ME: Welcome, Jilanne! Thank you so much for stopping by. Can you tell us a little bit about the book…and the story behind the story?

JILANNE: Thank you for having me, Vivian. It’s great to be here on Picture Books Help Kids Soar. I’d love to tell you a little bit about the bookAnd here’s

Plunge far below the ocean’s surface where billions of restless animals called zooplankton (including jellyfish) dwell in the Twilight Zone. Some are tiny, some enormous, and most are exquisitely beautiful. The setting sun cues their journey to surface waters for a midnight feast on trillions of tiny plants (and each other). It’s a daunting, perilous, nightly migration that transforms the dark ocean into a carnival of lights amidst a feeding frenzy in this eat before being eaten world—a journey that’s vital to all life on Earth.    

And here’s what inspired me to write the story:

When I was writing A River of Dust, I discovered that NASA’s CALIPSO satellite not only measured the North African dust that flies across the Atlantic, it also recorded the massive nightly migration of zooplankton in the ocean. First, I was astounded that a satellite could do this, but then as I learned more about these delicate, beautiful animals, and that they’re in danger, I knew I had to share what I’d learned with kids. The marine biologist from the Monterey Bay Aquarium Research Institute (MBARI) who reviewed THE OCEAN’S HEART at every step, Dr. Steven Haddock, was extraordinarily helpful. He’s taken blackwater photos of many of the creatures shown in the book (some that are so new to scientists, they have not yet been named). In fact, Khoa used MBARI photos and videos extensively to inform her illustrations since the action of the story is based in the Monterey Bay National Marine Sanctuary. And the luminous illustration used on both end papers is based on a satellite view of the bay. I also want to add that Haddock has a coffee table book (co-authored with Sönke Johnsen), called THE RADIANT SEA: Color and Light in the Underwater World, hot off the presses from Abrams. It features such stunning photography of these creatures, I knew I had to own it, and I plan to use it during school visits. 

No path to publication is totally smooth.
The manuscript had been out on submission for some time, and most editors said they liked the story but “didn’t have a vision” for how to turn the manuscript into a picture book, so they had passed. One of my longtime critique partners, Katy Tanis— a terrific illustrator—was getting frustrated with these responses, because, to her, it was obvious. So she put together a “vision board” using a variety of images from other books. It was amazing. When Carol Hinz expressed interest in the book, but said something similar, I asked my agent to send her what Katy had pulled together. Carol liked what she saw, and decided it was doable. So that clinched the deal.

  3. What a fascinating topic! I grew up in a small seaport town along the Pacific Ocean in Panama and so was exposed to a large ocean at a very early age.

    Congrats! Looking forward to enjoying your new book!
