Okay so I'm not entirely sure why I didn't like this book. Maybe it's because psychological thrillers aren't my thing. Maybe because I found it to be a little slower than I thought. Maybe the gimicky aspects of the book (the entire premise, unreliable narrator, hateable characters) just weren't pulled off well enough. Whatever it was, I didn't care for this book. But others might! If psychological thrillers are your thing, go ahead.
