In the breathtaking follow-up to We Who Have No Gods , Vic Wood struggles to understand her power and her heart in a world falling to tyrants. Reeling from her violent transformation into a witch, Vic Wood is determined to defeat Aren Mann, the leader of the Brotherhood. Lies, paranoia, and division consume the Acheron Order as it returns to a rebuilt Avalon Castle, and Vic finds solace in secret lessons with her mentor, Max Shepherd. But when Vic's training goes disastrously wrong, the consequences may challenge everything the Order knows about power. As the war between the Brotherhood and the Order escalates, Vic must navigate her strange new abilities and find the key to beating Aren Mann. Wrapped up in her growing friendships among the Sentinels and her irresistible connection to their leader Xan Galanis, Vic grows ever distance from her brother Henry, the reason she came to the castle in the first place. As Vic continues to challenge the Order's expectations, Vic must face the last thing she expects--a betrayal from the one person she thought she could trust.
