Definitely recommend this book. I had heard so much about it and thought that it was another book that was being overrated and over exaggerated. And then someone mentioned that if I liked Gone Girl then I would enjoy The Girl on the Train. So I gave in and bought the audiobook. Totally glad I did. 
 I thoroughly enjoyed the suspense and the mystery that surrounds the characters and their lives that are seemingly unconnected, but forever intertwined in the strangest of ways. The anxiety that Rachel feels throughout the entire story never lessens and actually continues to build right up until the very end of the book. It kept me on my toes, that's for sure. Not to say this book outdid Gone Girl, though. That last sentence in Flynn's novel takes the cake for me. But this story seemed to keep me a little more on the edge, maybe because the mystery wasn't solved until the very end? Either way, if you liked Flynn's novel, then The Girl on the Train is a pretty good book to move on to. I enjoyed the writing, but it is a little difficult to judge it based on an audiobook. By the sound of it, the novel flowed really well. However, the performers were spectacular, so it might have just been their talents that made it read well. If you are looking for a great audiobook, I highly, highly suggest this one because you will be entertained all the way through. 
 The downsides to the novel would definitely be the characters. Rachel kind of turns me off at times and then at other times I feel downright sorry for her. *Spoiler maybe*: She is an alcoholic who can't seem to get her shit together. Every time you turn a page, she is back at the bottle. She is one of those characters that you really want to root for, because you sit there and listen to all of the injustice in her life. But, yet, you hate her because she doesn't do a damn thing about any of it. She just takes it all. I hate those kinds of characters; the ones that just sit there and apologize without even trying to fix what's broken. Without even standing up for themselves. Yet, I liked her. It's all very confusing, that's for sure. The other characters: well...you'll just have to read the book to figure out my frustrations with them. All I can say is I found every single one of them disagreeable in some way. And then there are certain characters that Hawkins just stops writing about. That always frustrates me, when I feel as if there are loose ends that still need to be tied up. I also feel like once everything is solved, the end drags a bit. Even though there seems to be a lot of grievances, they are pretty tiny compared to my enjoyment of the book. 
 Overall, I thought it was great! A great mystery, a great thriller and a great story. Anyone looking for a fun audiobook should definitely look into listening to this one, and anyone looking for a good read can find it with The Girl on the Train.
