The sole survivor of a home invasion where she famously witnessed the death of her mother and sisters, Libby Day (Charlize Theron) lives with the knowledge that her testimony as a 7-year-old sentenced her brother, Ben (Corey Stoll), to life in prison for the horrific crime. Twenty-five years later Libby meets Lyle (Nicholas Hoult), the head of a group of true-crime enthusiasts, The Kill Club, who convince her to re-examine the events of that night. As new memories and old suspects flood back into her life, Libby begins to question her own testimony and sets out to discover the truth of her tragic past. Who did murder the Day family...?
I enjoyed the book and was hoping it would make a successful jump to the screen like Gillian Flynn's Gone Girl. Unfortunately, it is a by the numbers thriller than goes from one clue to another without any tension or red herrings to keep you on your toes. Charlize Theron just manages to look slightly annoyed throughout, probably more suited to a TV series than a film.
