The Fairtane family have ruled a small, cursed island for generations - until the night before Rowan Fairtane turns sixteen, when a too-successful attempt at usurping them leaves him the last surviving member of the family. With no plan for how to proceed, he assumes the morning will bring his death.
Only for his twin brother to be the one standing at the door.
Soren Fairtane disappeared five years ago, on the eve of his eleventh birthday, and was presumed drowned. Everyone knows that. His return to the island, though, isn't Rowan's saving grace at all. If anything it's about to spell disaster for them both, because Soren has a plan and five years have not really changed the insanity of his plans all that much.
With nowhere else to go, though, Rowan finds himself joining forces with Soren in his attempt to find a way to break the curse keeping everyone trapped on the island. But even if it has been five years since Soren vanished, it's not hard to tell that some things about him have changed... and the longer they spend searching for answers, the more Rowan begins to wonder.
What happened over the last five years? And is the answer to the island's curse right in front of him?
