The Girl on the Train
Paula Hawkins' novel is an addictive thriller to cuddle up with on the beach. If you liked Gone Girl, you'll definitely like this. Main character Rachel takes the same train every morning that allows her to watch the same people during their daily routine. She especially focuses on one couple and pretends that she knows them. One day she sees something shocking. She proceeds to tell the police but...will she regret that?
