"Follow Flynn the fly on an unforgettable glow-in-the-dark adventure under the sea!"—USA TODAY

A delightful follow-up to the New York Times bestselling The Fly Who Flew to Space, this glow-in-the-dark ocean book for kids follows Flynn the fly on an unforgettable undersea adventure that celebrates marine life, curiosity, courage, and discovery.

When Flynn the fly takes a wrong turn on the way to Cape Canaveral, frustration quickly gives way to wonder. Soon she is soaring beneath the waves, where coral reefs, mangrove forests, undersea mountain ranges, and a giant squid reveal just how much there is to learn about our precious planet.

Written by author, pilot, and philanthropist Lauren Sánchez Bezos, The Fly Who Flew Under the Sea is a beautifully illustrated picture book about exploration, biodiversity, self-acceptance, and the power of curiosity. As Flynn discovers the wonders of the ocean, young readers are invited to see learning differences as strengths and to follow their questions wherever they lead.

Perfect for curious kids, little explorers, classrooms, libraries, and family storytime, this deluxe hardcover picture book includes special features that make Flynn’s journey even more exciting:

• A glow-in-the-dark undersea spread that brings the deep-sea setting to life

• A removable jacket poster with glow-in-the-dark details

• A super-sized spread for an immersive reading experience

• A STEM-focused Undersea Glossary introducing sea creatures, habitats, and scientific concepts

• An inspiring message about confidence, conservation, and learning differences

A must-have for fans of children’s ocean books, STEM picture books, books about sea animals, and interactive children’s books, The Fly Who Flew Under the Sea invites young readers to dive deep, dream big, and discover the wonders waiting just below the surface.
