Department of Second Chances, Book 1

Heat Factor: Just when I was beginning to suspect it would be no sex… BAM
Character Chemistry: There was so much going on in the suspense plot, the relationship between the protagonists was relatively superficial
Plot: FBI agent + attractive single mother + serial killer
Overall: I’m not entirely sure how to reconcile my feelings about the first half of the book (chilling serial killer drama) with my feelings about the second half of the book (why are these characters so frustrating?)
