Avenging Angels: Bad Medicine. Avenging Angels, #4

Willow Knightley has just been through it with her ex-mooch of a boyfriend. But sadly, he's just the latest in a long string of men (starting at birth) who didn't treat her right. She decides her only recourse is to give up on men forever. The problem is, her friend/acquaintance/one-time bodyguard, member of the Nightingale Investigations & Security team, Gabriel Stark, has targeted her as His One. Gabe's been through it at the hands of women too, so he knows exactly what he wants. And he wants Willow. Willow states her case against them being an us, but she doesn't count on the fact that not only does Gabe love a challenge, he lives for them. Up against an onslaught from a man who rinses his own whiskers out of the sink, Willow might not stand a chance. But then, while the Angels are trying to figure out what's got one of their informants very jittery, she gets a hint that there are demons in Gabe's history, and she has to know. The bets are on. And luck favors a Stark.
