In the third book in the #1 New York Times bestselling Three Dark Crowns series, a queen who has long been dead makes a chilling return to Fennbirn Island.

Queen Katharine has waited her entire life to wear the crown. But now that she finally has it, the murmurs of dissent grow louder by the day. There’s also the pressing question of whether her sisters are actually dead—or if they’re waiting in the wings to usurp the throne.

Mirabella and Arsinoe are indeed alive, but they’re dealing with a nightmare of their own. Stuck on the mainland, where their powers have weakened, the girls are being visited by a specter they think may be the fabled Blue Queen, pointing her rotting, boney finger toward Fennbirn.

A queen on the throne, two on their way home, and an unexpected renegade who’s gone to ground. The crown has been won, but these queens are far from done.
