He'll do anything to keep her. She'd do anything to escape. Rhiannon is dying--of what, she doesn't know. Kept protected by her family in their remote seaside cottage, she spends her days searching for a cure. Her world is torn apart, however, when a fae King of the Dead invades her home. Cold and cruel, Drystan offers her a choice: descend to the underworld as his bride or watch her family die. Trapped in a twisted bargain, Rhiannon is thrust into a world of withered gods, scheming courtiers, and ancient magic, but she refuses to be a pawn in a game she never agreed to play. She attempts over and over to run away, until Drystan offers her a new bargain: escape his deadly labyrinth, and he will set her free. Fail, and become his bride. But in a court where every promise has teeth, Annon must make an impossible choice: return to the home she's always loved or claim her place in a world where she might finally belong.
