For a long time alpha werewolf and ranch owner Aiden Mitchell has desired the curvy, vivacious Nikita Blakemore, alpha female of the Blakemore pack. He will have her as his mate and no other. To force her hand, Aiden maneuvers her into hosting a Mating Challenge, the ultimate warrior competition for werewolves, where males fight for the right to mate and breed with a female alpha. Fiercely protective of his future mate, Aiden will do anything to make her his own, even fight to the death.

Masquerading as her twin sister, Nia Blakemore knows she is the one Aiden wants in his bed. Nia has dreamed of the handsome cowboy sweeping her into his strong arms and consummating the passion consuming them both, even though he thinks she is Nikita, the true alpha female. Nia must try to keep Aiden from discovering the truth to protect her frailer, gentler twin. But Nia and the real Nikita hide a secret far more deadly than the charade they have pulled off for years, one that can kill Aiden and any healthy male who sets foot upon their land…
