The Familiar Dark by Amy Engel

A very dark murder mystery of two twelve year old girls. One of the moms is a single mother whose own childhood with a meth-head mom in a trailer crowded with mom's various boyfriends was something she did not want for her own daughter. Her brother turned out ok and became a cop but once Eve's daughter and friend are found in the park with their throat cut everyone's life goes off the rails. Eve has nothing to live for except vengeance. The book moves at a fast pace but I just didn't like any of the characters enough to care about the outcome. It just left me feeling sad for all involved.
