One will betray her.
Still reeling from the events of Greece, the hunters find themselves targeted by demons and werewolves. As they try to figure out who has marked them for assassination and why, Shanna learns more about who the mysterious figure Diana was, and about the people she is hunting alongside. After the dust settles, they will never be the same again.
