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.

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.
