Mating with a human is strictly forbidden.
Alpha wolf-shifter Dane has been forced to stand by and watch the love of his life date another. Trisha is off limits to him because she isn't a supernatural and she's not allowed to know his secrets. When he realizes she's going to take the plunge and marry another - a human - he can't fight his inner beast any longer. It wants to claim her and he's going to let it.
