My librarian suggested Dark Places by Gillian Flynn. I've been reading this sinced Saturday and I'm enjoying it. It reminds me of the premise of the Aurora Teagarden books by Charlaine Harris. It's about a girl whose family is murdered and she joins a Kill Club that investigates murders both old and new.
I've got a couple of books waiting for me to pickup at the library. When those are finished, I'll probably put Sharp Objects by Gillian Flynn on hold.
