I'm almost finished with Paula Hawkins' mystery, thriller novel The Girl on the Train, and wow. It's very much in the same vein as Gone Girl - mystery, shifting perspectives, totally unreliable and unlikable narrators all acting like assholes in some fashion. Trust me, you're going to love this book. It's good and it's dark and it will grab you like the hand of a buried corpse reaching out of a shallow grave to yank you in. If, like me, you can't decide what to read next, this should be your next read.
