A mysterious signal. A century-old sea cave. And a glowing clue that could change the ocean forever.
Welcome back to this thrilling second installment in the Kai Flynn Adventure Series — where high-tech STEM meets history, mystery, and adventure on the Southern California coast.
After uncovering a secret lab beneath the San Diego Zoo, 14-year-old inventor Kai Flynn returns for a new challenge. This time, the clues lead beneath the waves — to an old map, a strange signal from deep in the cove, and a trail left behind by the legendary marine scientist, Dr. Elena Morales.
Joined by his daring 10-year-old sister Emma — famous for her mismatched socks, sharp wit, and impeccable timing — and Quantum, their lovable quadruped robot sidekick, Team Flynn dives into underwater caves, glowing sea labs, and encrypted codes hidden in the tides.
Armed with clever gadgets, codes, and curiosity, and with help from their scientist parents and a fearless grad student, they must outsmart greedy treasure hunters and crack a century-old riddle before the next tide rises.
Perfect for fans of Spy School, MacGyver, The Mysterious Benedict Society, and Ada Twist, Scientist.
