Tempted in the Night (Night Slayer, Book 3)

For Jessica Winslow, the only good vampire is a staked vampire. Driven by revenge, the fiery brunette takes insane risks to destroy the undead wherever she finds them. Now she pursues her most fiendish target ever--and finds herself competing with the razor-sharp street smarts of a dangerously seductive man...
Detective John Boehler has no problem dealing with vampires--not even the city's newest bloodsucker, a notorious serial killer John had failed to bring to justice. He does have a problem with the attractive vampire-hunter recklessly following the murderer's trail. But when John falls prey to a power he could never have predicted, Jessica must tempt his now all-consuming hunger--and taste her own uncontrollable desire.
