I think everyone should read The Girl on The Train, especially if they loved Gone Girl. It's about Rachel, a girl who sees a couple on her commute. Then one day she sees one of the people from the couple kiss another person. The next day they go missing. The story is told by 3 different perspectives, all characters you absolutely can't trust. It's an insane psychological thriller that's seriously addicting and the kind of book you can't put down.
