Redeemed by Desire: City of Sin

Neo has lived for the last two thousand years knowing he would never find his mate. There could be no mate for him. He had long since come to terms with his curse. Then Gwen came into his life. He could feel that she was his mate, but how? 
Gwen was here to do a job, not to get laid. But she hadn’t counted on finding her mate. Could she still do her job or would her alphas send someone to replace her? Can she figure out how to make it work or will it cost them both everything?
