Alpha's Challenge

Mark me and make me yours.

As an unmated alpha, Cade was beginning to believe his entire life would be dedicated to the pack. He'd do anything for his pack family, but his life isn't complete without someone to share it with. He didn't expect to finally find his reason for being in the heart and soul of his greatest enemy's sister.

Dr. Grace Pellini has never felt so isolated and afraid. Ever since her rogue brother threatened the existence of wolf and human alike with a viral weapon, she had no choice but to cut all ties with her pack. But now Grace has something new: Cade Warden, whose body and exhilarating scent make her come undone. In him, she's not only found her destined mate, she's also rediscovered herself, and her place in a world at war.

But the Cascadia wolves are not so unquestioning as Cade is of Grace's loyalty, and their suspicions are posing a dangerous threat. Now, to defeat a madman and end the war, Cade and Grace have only each other to trust-by finding their ultimate strength in the power of desire.
