The dead naked woman splayed across the cover of this book kept me away from it for a while. I enjoy the medical part of Gerritsen’s medical mysteries but she sometimes crosses the line into too gross and too gory for me. So, I thought that this story about a mudered nun might be icky. And it was, a little. However, it was also a very subtle and engaging whodunit including two strong female characters dealing with their own personal issues as well as the complicated issues of this case. It had more depth and less timeworn mystery cliches than some of her other books and the interplay of characters -- most of whom are interesting, even the minor players -- meant that it was an engaging read from start to finish.
