Even as the two struggle to balance a relationship in a world that still frowns on vampire-shifter cooperation, the tentative alliance between the species is shattered by an unexpected attack. Old wounds are stirred, and Derek's relationship with Kaname is threatened. Can their bond withstand the weight of divided loyalties?
