Cat Barahal and her beloved cousin Bee think they have reached a safe place to shelter. But the Cold Mages who are conspiring to take them prisoner are closing in. The warlord who hopes to conquer all Europa is convinced their destiny is to aid him, whether they want to or not. And the man Cat was forced to marry is back, as vainly arrogant and annoyingly handsome as ever. Worst of all, as Hallows’ Night approaches, powers hidden deep within the spirit world are rising. Cat must seek allies against these threats and figure out who to trust, for if she makes the wrong choices, she’ll lose everything. Only one thing is certain. When Hallows’ Night comes the Wild Hunt will ride— and it feeds on mortal blood.
