Rachel rides the commuter train to and from London every day. The train stops in roughly the same spot each day and Rachel enjoys watching the people who live near the stop. She lives vicariously through their seemingly perfect lives, even as her own life spirals out of control. Her observations from the train lead her to involvement in a missing persons case. Unfortunately, Rachel has a drinking problem and can’t always remember what she has done. No one is quite what they seem in this psychological thriller. There are plenty of plot twists to keep the pages turning.
