The Church of the Dead Girls by Stephen Dobyns

I just finished reading this for the second time. This is an extremely well written book. As you can guess from the title it's not a happy story so it may not be for everyone. It's the story of the reactions of the citizens of a small town to the disappearance of a child. When the first girl disappears they all hope the criminal is an outsider but when a second girl goes missing they are forced to admit that it must be someone they see everyday. You'll enjoy this if you like mysteries or thrillers.
