"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.

• 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.

About The Author

Long before Emmy Award-winning journalist, pilot, and philanthropist Lauren Sánchez Bezos was a NY Times bestselling children’s book author, she was a little girl with big dreams. Growing up in Albuquerque, New Mexico, she looked to her father, a former flight instructor, and dreamed of one day becoming a pilot. Watching him ignited Lauren’s passion for aviation. After a long career in journalism, Lauren finally got her pilot’s license in her 40s—proving you are never too old to chase your dreams. Years later, Lauren can see her own kids looking to the sky with wonder. That experience as a mom, coupled with her love of storytelling and adventure, motivated Lauren to write The Fly Who Flew series. Lauren hopes this new adventure will inspire kids to follow their dreams and see that learning differences can be a superpower.
