Spoiler free review! 
 This is the first thriller that I've ever read. I remember seeing the cover at Costco, a long time ago now, and being intrigued by the cover. I love how the text gives you the sensation that you are moving, as Rachel does every morning during her commute on the train. Rachel is the "girl on the train." 
 I was gifted the book during Christmas, and after I started reading it I couldn't put it down. I needed to know what happened next. I needed to know who was telling the truth, what was being hidden, whose word was reliable and whose wasn't. As much as I love my favourite books, this type of book produces a different kind of urgency to it while you read - there's a lot happening, and from different points of view, and you're trying to figure out the real story. Because everyone knows that there's more than two sides to a story: my version, your version, and what really happened. That's the kind of thing happening in this book. I've heard some people complain about the timeline of the story, but I think the way it is written is crucial to how the story unfolds for the reader. Paula Hawkins wants us to learn specific things at specific times, and that becomes obvious the closer you get to the ending of the novel. 
 In short, The Girl on the Train is the reason that I went on to read You by Caroline Kepnes as soon as I laid this book down, and also the reason that I bought 4 more thrillers once I finished that book. Because of this book I've found a new genre that I really enjoy - one that I never really gave a chance before. 
 I highly recommend giving this book a read - even if it is your first thriller, as it was mine. You might become addicted to thrillers as well! (*_*) 
 My rating: 4.5 / 5
