The Link That Binds — Dawn H. Hawkes

Jace, a shapeshifter, is held captive by vampires after a mission gone wrong. A turn of events puts him in close contact with Link, the very same human that facilitated his capture. With Link working for vampires, can Jace cope with the fact that Link just might be his mate? Link never wanted to work with vampires, but led astray by his curiosity and the promise of money, he is now stuck in a dangerous arrangement he can't escape. Meeting Jace might be his ticket out. He sure as hell isn't going to do what the vampires tell him to when they request he find a "cure" that will eliminate all shifters... and use Jace to do so.
