Jace Warden is sent to the Shiftertown in Austin to find a way to free all Shifters from their Collars. But pulling off the Collars can cause Shifters to go mad or kill them outright. In Austin, Jace meets Deni Rowe, a wolf Shifter with troubles of her own—she was deliberately run down in the road, and while her body has healed, she still has episodes of total memory loss during which she retreats into her pure animal self. Jace has never met anyone like Deni. Courageous and beautiful, she volunteers to help him test the Collar removal. And as Deni and Jace work together, they feel the mate bond begin. But can Jace help Deni believe she can heal enough to be anyone’s true mate?
