And that..... was an incredibly mediocre thriller. 
 I don't even know where to begin. This book and its characters have more issues than all the seasons of Gossip Girl combined. Except I liked Gossip Girl. 
 This is the story of three women who share no connection to each other except that they've all lived in the same suburban neighbourhood by the train tracks and they're all damaged enough to be unstable and that is exactly what they are throughout the novel. 
 I have never understood how people can blithely disregard the damage they do by following their hearts. 
 This is something Rachel, the Girl on the Train , says in the early part of the novel. It really resonated with me, except that is exactly what Rachel does. Blithely follow her heart, be a pathetic excuse of a human being, regret it the next day, then do it all over again. I have never been more annoyed with a protagonist as much as I was with Rachel while reading this novel. 
 Every character in this book was the human version of a migraine. Rachel's internal monologue oscillates between being meaningful and being downright tedious at times. The scenery is bland. Looking at the world through Rachel's eyes is like looking at a grimy Polaroid while wearing shades that have a layer of dirt caked on them. 
 All in all, this was a pretty average thriller. If it can even be called that. I almost enjoyed The Cuckoo's Calling by Robert Galbraith more than I enjoyed this. I'm still going to pick up Into the Water by Paula Hawkins though. Probably because the cover is prettier. Whatever.
