On the sharp crags of tiny Tillings Island lies the secret of Izabella Rae Haywood’s sixth birthday. That night, her father vanished, taking her voice—and the truth of what really happened—along with him. In the autumn of 1974, after eight long years of unsuccessful psychiatrist visits and silence, Iz’s mother packs up the tattered remains of their life, determined to return to Tillings in one last attempt to reclaim Iz’s voice—and piece together the splintered memories of the day her words ran dry. But when the residents of Tillings greet them with a standoffish welcome, it becomes clear that they know something about Iz, and the father she adored, that she does not.

Now, as the island’s annual Yemayá festival prepares to celebrate the ties that bind mothers to children, lovers to each other, and humankind to the sea, Iz must unravel the tangled threads of her own history . . . or risk losing herself—and any chance she may have for a future—to the past.
