Marlin dreams of becoming the fastest merperson in the sea.

He loves racing the currents, exploring coral reefs, and chasing adventure through the wide blue world beneath the waves. Most days, he follows the rules of his people, helps with chores, listens to the elders, and stays far away from the dangerous waters known as The Deep Cut.

But one reckless race with his friend Coraline changes everything.

A powerful current sweeps them into a mysterious, glowing cavern where the water twists and surges in unpredictable ways. The elders warned them never to go near the Deep Cut, and now Marlin understands why.

Just when he thinks the danger is over, Marlin faces an even greater test.

A human boy has fallen into the sea and is being pulled down by the same deadly current.

For generations, the merpeople have lived by one unbreakable rule: never reveal themselves to humans.

Now Marlin must decide: follow the rules or risk everything to save a life.

From award-winning author Alison Gieschen, creator of Seanna: A Mermaid's Tale, comes a story of courage, choice, and the power of doing what's right, even when it's hard.

Includes a glossary of ocean terms for young ocean explorers!
