Dark Places by Gillian Flynn

A dark (as the title states), depressing novel with pretty much no sympathetic characters, this is the second novel by Gone Girl author Flynn.  The main character here, Libby Day, was witness to her mother and sisters being murdered when she was a small child.  In court, she identified her brother as the killer.  Over 20 years later, Libby begins to doubt that testimony...did she really see her brother kill three members of her family or did she just believe she had seen it?  Libby begins a quest for self-discovery that will take her life into even more dark places than before.

First of all, Libby is not a nice person.  She's a thief, she can be violent, and she only begins to question her brother's innocence after stumbling on a group of true crime addicts who offer her money for trophies from her past.  Aside from Libby, the novel is also told from the point-of-view of the mother and the brother (both of those POVs are set before the murders).  But, like Libby, neither the mother nor the brother are characters the reader will want to relate to.  The brother, Ben, gets involved with Satanism and a VERY bad crowd of friends.  And the mother sits idly by while her family crumbles around her. 

See...it's a VERY dark story.  But, if you can get past all of that, it is a well-written, edgy piece of fiction that really does keep you reading.  Unlike a lot of contemporary thrillers, this one has a solid foundation, as well as great character development and a pretty decent ending.
