Night's Kiss (a bit of a spoiler)

Last night I finished reading Amanda Ashley's Night's Kiss. Although I've always enjoyed her vampire romance books, this one...well, let's just say that I wasn't 100% thrilled with it. The first part of the book was about the hero traveling back in time to save the heroine from being burnt as a witch (which she actually is). He brings her back in time, and there is where the book gets monotonous. That is until the warlock (the villain) enters and the pace of plot picks up. He seeks vampires to "study" (in very nepharious ways) their blood, when in reality he wants to become immortal like them. The ending was a bit forced with the whole "finding a girl giving birth in an alley", etc.
