One Foot in the Grave
by Jeaniene Frost, 2008
Series: The Night Huntress Series

"Half-vampire Cat Crawfield is now Special Agent Cat Crawfield, working for the government to rid the world of the rogue undead. She's still using everything Bones, her sexy and dangerous ex, taught her, but when Cat is targeted for assassination, the only man who can help her is the vampire she left behind.

Being around Bones awakens all her emotions, from the adrenaline rush of slaying vamps side by side to the reckless passion that consumed them. But a price on her head - wanted: dead or half-alive - means her survival depends on teaming up with Bones. And no matter how hard Cat tries to keep things professional between them, she'll find that desire lasts forever ... and Bones won't let her get away again." (From JeanieneFrost.com)
