I'm torn on how I felt about this one, honestly. I really loved The Girl on the Train, so I had extremely high expectations.. and unfortunately, this just fell flat. I think what bothered me so much about it was that it had so many different characters, and the story flips back and forth between each one, so it was hard for me to follow and keep track of who is who.

Nel leaves behind a teen-aged daughter and a sister, whom she hadn't spoke to in years. Secrets start to unravel, and everyone realizes that there may be more to these deaths than what was originally seen.
