The FRLWDS Book Club had a great discussion with this book. Most of us loved the dark but thrilling and fun roller-coaster ride!,,,,,except for the ending. We felt like it was unrealistic and basically set the author up for a possible sequel with it's "conclusion". The ride with these psychos was crazy one with your allegiance changing with the unexpected and crooked plot twists. Most of the characters without a moral barometer- or just plain nuts!... with the exception of the police officers (we really liked Boney). We have a mental health nurse in our group - it was interesting to get her perspective! Most of the group agreed they would have to pick up the sequel- if there is one. And we are very much looking forward to the movie- but were split on the casting of Ben Affleck- maybe Bradley Cooper instead? Oh well- Bradley can't be in EVERYTHING- dang.
