I got this novel quite a few months ago and didn't pay much attention to it. I just finished reading it yesterday after all those months and I found it quite compelling - at first I thought the plot was pretty weird - young women were being murdered by crucifixion to atone for their "sins." While the reader knows immediately who the killer is, it is not clear exactly what the motive is. It takes the San Diego Police Department detective Sami Rizzo and her partner Al Diaz much longer to figure out - will one of them end up "on the cross?" There is a sequel to this book titled "Resuscitation" which I actually read first but, no matter, I really didn't associate the two - at least not right away.
