A romance author takes a trip to her childhood beach home, but her summer is upended by the startling return of a deceased childhood friend, newfound love, and . . . sea monsters?

The USA Today bestselling author of On Earth as It Is on Television returns with an earnest, humorous novel on the pressures of adult life, the magic of childhood, and what swims in between.

As a lonely ten-year-old resident of Pearl Island, Jenni Farrow befriends Timmy Caruso and together they enjoy a glorious summer of swimming, fireworks, and carnival rides. (Not to mention rescuing a strange sea creature from a tidepool). Then, one late summer day, Timmy disappears.

Thirty years later, Jenni—now Jenn Lanaro, bestselling author of the Philipia Bay action-romance series—is desperate to escape the fatigue of her career and her soon-to-be-ex-husband. With her Pokémon-obsessed children in tow, Jenn rents a summer house on Pearl Island. But shortly after she arrives, a boy emerges from the nighttime sea. His name, he says, is Timmy Caruso. He’s ten years old. And he’s on a mission to save the world.

In the days that follow, Jenn grapples with work deadlines, her own spirited children, the mysterious boy-from-the-sea, and her burgeoning interest in a very sexy contractor. But when alarming events unfold along the coast—shark attacks, tidal waves, a proliferation of sugar-addicted sea creatures, and a terror out in the deeper water—she wonders if just maybe the young boy knows what he’s doing after all?
