I Hunger for You
By Susan Sizemore, 2005
Series: Primes

Mia Luchese comes from a long line of vampire hunters but has never believed in the supernatural. When she's attacked by vampires, though, Mia must accept her family's dark legacy. What she doesn't know is that sexy S.W.A.T. team leader Colin Foxe, her rescuer and former lover, is also a vampire.

Colin doesn't want to mate with a mere mortal, but his attraction to Mia is blistering. To get to the bottom of the attack on her, he is forced to reveal his real identity--and Mia hers. But a generations-old battle that should rip them apart cannot break the bond that has their souls hungering for an eternity of ecstasy in each other's arms.... (from Susan Sizemore's website)
