I should probably have known that I would be meh on this because hardboiled detectives are not my favorite, but also I wanted it to be interesting about theology in a way that it was...not.

Part of the reason I disliked it is that I find "this woman does terrible things because MEN ARE EVIL" to be a fundamentally uninteresting story. It's basically the women in refrigerators story, but in reverse and, like, why? Also I COMPLETELY missed why the killing spree happened. Like, what was the point? How was it supposed to help? The only read I could find on it were religious people are crazy and what a boring take?

The other thing that bothered me is, and I'm not entirely sure how to describe this, the shallowness of the faith. And I don't know if that's because my own faith tradition feels deeper because I'm in it and I don't see the depths here or whether the author's take on faith itself is also shallow and could have more behind it.
That was the part I found so disappointing. I wanted a story about faith and murder and I got a story about murder in a religious environment. They are not the same.
