She came to the island to escape the storm. He is the lighthouse keeper who is the storm. Adrian lives by rules carved in salt and silence—obey the house, never ignore the horns, and never say the word that can end everything: Nocturne. But Selene isn’t here to follow rules. Drawn to his scars, his obsessions, and the secrets buried in his walls, she discovers desire can be as dangerous as the council hunting them. The house is full of horns that lie, the cliffs wait to claim them, and Adrian’s hunger is a darkness that wants to keep her forever. To survive, Selene must decide if she’ll surrender to his vow—or break it with a single word.
