Habits of the Sea is a lushly written, beautifully emotional story about a love powerful enough to cross the boundaries of time, and even more so, about what it means to choose love over and over again.

This lovely book opens with a devastating scene. On a stormy night in 1952, on an island in the
Outer Hebrides of Scotland, a grief-stricken man buries his wife and stillborn babies. By the next morning, the storm is gone — and so is the piece of land where his house and farm once stood. There’s no wreckage to be found; it’s as if the land itself has broken off and disappeared.

Over the years, the legend of Saltwell Island spreads — how Clay Lockhart’s grief was so intense that it split the ground apart. Fishermen and sailors would share the story of spotting:

… the newly formed island with its white house perched atop a stony outcropping, drifting out into the farthest reaches of the deep gray Atlantic.

Many years later, in 2007, 12-year-old Ellie Mills is living with her grandmother in a small coastal village in Nova Scotia when she hears a strange noise during a storm. Running outside, she sees what she assumes to be a shipwreck stuck against the rocks along their harbor, and without much thought, takes their small boat out to investigate. But it’s not a shipwreck — it’s an island, drifted up on the rocks. And there, Ellie encounters Clay Lockhart, a man who appears to be in his 30s. She spends just a few hours on the island, warming up after sailing through the rainstorm, but when she returns home, a full week has passed.

Ellie’s life is forever changed. No one believes her tale of a floating island, and she’s mocked by her friends and sent for psychiatric care by the adults who believe she’s created a fantasy as an explanation for a traumatic event. And over the years that follow, Ellie manages to convince herself that her journey to Saltwell Island wasn’t real.

But almost twenty years later, having left Nova Scotia and her troubled past behind, Ellie hears that the fabled island has been spotted by a passing cruise ship way off in the Atlantic. Needing to settle her own mind once and for all, she flies off to the last known location… and once again, finds Saltwell Island — and Clay Lockhart, who hasn’t aged a day.

The heart and soul of Habits of the Sea revolves around Ellie’s connection to Clay, and to the life and love they gradually discover together. The longer Ellie finds herself on Saltwell, the more she’s able to see how so much of her adult life was an attempt to shelter herself from risk, to protect herself from the possibility that perhaps she did once experience something extraordinary. To Clay, it’s only been a year since an odd little girl first washed up on his island; clearly, Saltwell Island has become separated not only from the land it was once attached to, but from time itself.

A thread of passion and purpose runs through every moment of Ellie’s time with Clay. Even before love develops, there’s a connection between them, and Ellie feels grounded in this strange place more than she’s every been anywhere else.

I sleep now each night as if I’ve never really slept a day before this. A restfulness that feels childlike, something from a storybook: She slept so deeply that even the wolves could not wake her. And when she finally rose with the sun she was restored to who she was always meant to be. It’s the kind of sleep that I won’t be able to describe once I’m back in the real world. There are no words for it. Unless you’ve felt it, unless you’ve been pulled into your dreams like sinking below a waterline.

Life on the island is simple and wonderful. Ellie and Clay tend the gardens, chickens, and sheep. They live peacefully, relying on the bounty of the sea and the island for sustenance. The island drifts where the sea takes it; there’s no navigation or power to control its voyaging. Some seas are calm, some full of danger. There are warmer days as they drift south and pull mangos from trees along the shores, and bitterly cold days where they rely on the cellar full of preserved foods to get by, until they drift again to someplace more nurturing of growing things once again.

As time passes, Ellie is faced with unbearable choices. She knows that time passes differently on the island — how long has she been gone from the “real” world? What does this mean for her grandmother and the almost-fiancé she left behind? If she can find a way to get back to a mainland somehow, should she? But how can she leave Clay and everything he’s come to mean to her? In a deeply visceral way, Ellie is forced to reckon with understanding who she is and where she truly belongs, and must grapple with a choice about sacrifice and destiny before committing to a future — because she knows that if she leaves the island, she’ll likely never have the chance to find it — and Clay — again.

Maybe we’re not meant to know what’s right or wrong. To know which path to choose. Which life. Maybe the no-knowing is the point. Because maybe we’re meant to be a little reckless.

Habits of the Sea has a Brigadoon-ish feel at times — Saltwell Island is a mystical, fairy tale-like place that magically appears for a brief time before disappearing off into the unknown. How can someone leave the place they feel truly alive, knowing they may be leaving it forever? I was reminded in certain ways of Outlander as well, where a character displaced from her own time must decide in which world she truly belongs.

The sense of building emotional entanglement is gorgeously written. We readers can feel how complicated Ellie’s inner life has become — the conflicted sense of loyalty, the desire, the questions about belonging, obligation, and fulfillment. The pull between Ellie and Clay feels real and true; their connection leaps off the page.

He breathes and the air seems to change — subtly, like a sudden drop in barometric pressure, atoms dividing, seconds splitting. The line between before and after unspools. Right from wrong. Him from me. It all feels perilous. And unnamable.

In the latter part of the book, the storyline seems to veer from magical realism — the unworldliness, a place out of time, almost like a visit to a faerie kingdom — toward speculative fiction, as the plot moves in a direction that surprised me, yet makes complete sense in the grand scheme of the overall narrative. Without going into detail, while I didn’t expect this, I ended up feeling that the book as a whole operates on a grand scale that absolutely brings every bit of the characters’ arcs to a point of perfect resolution.

Habits of the Sea is a book that will be haunting my thoughts and dreams for a long time to come. With gorgeous writing, a plot that wraps a reader in layers of a reality that’s magical yet intensely tangible, and characters who we come to care about deeply, this is a book filled with wonder and beauty. Once I started, I never wanted to look away.

Don’t miss this incredible reading experience.
