This book is a typical who-dunnit, brilliantly plotted. The story revolves round Anna. She is the driver in an accident with terrible consequences and her feelings of guilt and inability to forget thread through. Her relationship with her boyfriend is changed and she decides to move right away. Things still go wrong and you can almost feel her suffocating paranoia and sense of no escape. She is stuck in a hotel with seven strangers, who all turn out to have problems of their own. These are gradually revealed. The author very cleverly leads you to believe the stalker/killer is one person then another. There are several twists and red herrings and a chilling finale. A book I could not put down until I finished it.
