Fleeing his captors, Subject Four wanders the wilderness, trapped in his monstrous form halfway between man and wolf, until one moonlit night he catches the scent of his mate. His destiny. The only problem is, she's a trap... Bonnie Randal, med student and frustrated virgin, has never known the touch of a man or the pleasures of the flesh. Kidnapped and bound, she's about to find out what she's been missing. Four is certain he used to be a man, before he was captured and imprisoned, subject to terrible experiments and his memory erased. The nearness of his fated mate brings clarity and he's convinced that if he mates with Bonnie, he'll become a man again. Bonnie isn't so sure, and the pleasure of his beastly body leaves her even more uncertain that she would want him to turn back. With their captors on their heels, will Bonnie choose her human life, or her beastly love?
