Habits of the Sea: A Novel

“Shea Ernshaw is the queen of storytelling that is as haunting and dreamlike as it is intimate and grounded.” —Melissa Albert, New York Times bestselling author

The second adult novel from New York Times bestselling author Shea Ernshaw, in which a woman rediscovers the mythical island she stumbled upon as a child—and the man she once met who apparently hasn’t aged—and must choose between the life she’s built and a love that defies the laws of time and nature.

The night Clay Lockhart’s wife dies, a violent storm tears their home—and the eight hectares of land beneath it—away from the Scottish coast, sending it adrift into the Atlantic. Thirty years later, twelve-year-old Ellie Mills discovers the fabled floating island off the coast of Nova Scotia and finds Clay still living in the weatherworn farmhouse perched on its highest hill.

When the island vanishes overnight, Ellie is left questioning whether it ever existed at all. But decades later, the island resurfaces—and Ellie, now in her thirties, returns, determined to uncover the truth. What she finds is even stranger: Clay hasn’t aged a single day.

Faced with the impossible, Ellie learns that some mysteries aren’t meant to be solved—and that a life shaped by wonder may hold more promise than one bound by certainty.

Spanning centuries and coastlines, Habits of the Sea is a haunting, romantic journey through time, memory, and the invisible tides that pull us home.
