Dark Places is a novel about a women (Libby) whose mother (Patty) and 2 sisters were brutally murdered by her older brother (Ben) 20 years ago, in the early hours of January 3, 1985, when Libby was 7 years old. It was her testimony that put him in prison. While low on cash, she is approached by a group who believe her brother is innocent and begin to pay her to investigate. She discovers there is lot more to that day and night than she ever imagined. 
 The story is told in three parts, the chapters alternating between modern-day Libby, 1985 Patty and 1985 Ben. 
 This is an enthralling thriller that kept me turning the pages. I wouldn't say the ending surprised me, it is not too difficult for guess for someone like me who reads a lot of mysteries. But I enjoyed reading it, it is well written and a good story. Certain characters really irritated me, in a way where I just want to go inside the story, grab them by the shoulders and yell "what are you doing, omg no stop, is there something wrong with you?!" Which did make certain parts more difficult to read. 
 All up, I heartily recommend this novel.
