This book was really disturbing and not in a good way. The heroine needed some serious help and some serious soul-searching. She made a lot of questionable choices, especially in regards to her 13 year old sister. The mystery took a backseat to her family drama, so when everything was revealed, it was too late and too abrupt.
The only other book I had read by this author was Gone Girl and I did like that one. I may try about book but am in no hurry to do so.
