Kenzie Butler is in love with the man who saved her life eight years ago. Her problem? He's a Siberian were-tiger with the ability to scent his mate, and she wasn't it. For years they lived across the hall from each other, helping one another with the aftermath from being tortured in a science experiment gone wrong. With each passing day, she falls more in love with him, even while knowing that one day Tiberius will find his true mate. Tiberius Petrov leads a shadowed life. Kenzie is the only thing standing between him and the gruesome fate awaiting any shifter who goes rogue. For eight years the sound of her voice, the sweet intoxication of her scent, and the soft feel of her skin have kept him from turning down darker paths. But he'd always believed she could never be his. His nose was supposed to tell him who his perfect mate is, but it lied. He didn't know if it was possible to develop a mate scent. All he knew was one day Kenzie didn't smell like his mate, and the next day she did. Even after her scent changed, she kept insisting they were perfect as just friends. After Kenzie survives a mysterious were-bear attack in her place of work, Tiberius learns the scientists altered more than his state of mind. Just when he thought he could take Kenzie as his mate he discovers he could be the biggest threat to her life.
