Award-winning author Juliet Marillier's "lavishly detailed"* Blackthorn & Grim series continues as a mysterious creature holds an enchanted and imperiled ancient Ireland in thrall.
Disillusioned healer Blackthorn and her companion, Grim, have settled in Dalriada to wait out the seven years of Blackthorn's bond to her fey mentor, hoping to avoid any dire challenges. But trouble has a way of seeking out Blackthorn and Grim.
As Blackthorn and Grim begin to put the pieces of this puzzle together, it's apparent that a powerful adversary is working behind the scenes. Their quest is about to become a life and death struggle--a conflict in which even the closest of friends can find themselves on opposite sides.
