Alexei appoints himself Kieran’s shadow, protector, and personal tormentor. But the tension simmering between them is more than just political. Behind closed doors, the power dynamics shift. Kieran discovers that the only place he can truly let go of control is in the arms of the savage wolf who wants to claim him.
