If you're in the mood for a thrilling “who done it,” I would highly recommend Dark Places by Gillian Flynn http://gillian-flynn.com/dark-places/
The story is about the murders of the Day Family who were brutally slayed in their Kansas home. Seven year old Libby Day escaped the massacre which her 14 year old brother, Ben, was convicted of doing. The action takes place 25 years later when Libby begins to question whether her testimony against her brother was really true.
In need of money, Libby joins up with a “kill group” interested in the murder. Libby's quest to arrive at the truth while earning some money on the side has her re-visiting some very dislikable characters including her own father. Everyone involved in the story has a secret past, leaving the reader to suspect each one of the murders. This is what makes the story so compelling.
Dark Places is equally as thrilling as with Flynn's best selling novel, Gone Girl http://www.amazon.com/Gone-Girl-Gillian-Flynn/dp/0307588378
Gone Girl was turned into a hit movie starring Ben Affleck and Rosamund Pike and just this month Dark Places was released with Charlize Theron heading up a star studded cast http://www.imdb.com/title/tt2402101/
Prior to writing these bestselling novels, Flynn worked at Entertainment Weekly, doing reviews for top movies around the globe. To learn more about Flynn, visit her website: http://gillian-flynn.com/
I gave Dark Places 4 out of 5 stars on my Goodreads page https://www.goodreads.com/author/show/4673038.Adele_Park
Flynn's website says she's busy playing Ms. Pac-Man in her basement lair. One can only hope that while Flynn is down there she spares a few minutes to write another novel!
