Bluebird, Bluebird by Attica Locke.
I found this author on the New York Times fifty best mystery/thrillers. I think this was the only one in the top ten I hadn't read. OMG, if you're a fan of Lehane, Flynn, Hawkins, Cosby, or Abbott then you need to add this to your list. Great setting, tricky thoughts because some of it is in the free indirect style. The voice and the characters are engaging. Totally deserves a spot on the list.
