In terms of plot all you need to know is that a girl (woman really) with some personal troubles and an active imagination commutes to London via the train every day. While on the train one day she notices something unusual. That’s all I really feel comfortable revealing. The less the reader knows about the plot the more addicting the read. I will say this; the story grabs your interest from the beginning and doesn’t let go. My only slight complaint is that I suspected where the story was going fairly early on. I read these types of books just looking for the inevitable “twist”. I was one of those people unsurprised by the big reveal in Gone Girl. However, just because I also spotted (or at least suspected) this one in no way hampered my enjoyment of the book.
If you’re in the mood for a psychological thriller do yourself a favor and get this book. You won’t be disappointed. Best read on a stormy weekend with a drink by your side, for effect of course!
