This is one of those books that was just ''meeh'' for me, hence the 3 stars. It wasn't super good but it wasn't super bad either. 
 Let me list down some things: 
 * I have read Gillian Flynn's other novels (Dark Places and Gone Girl) and absolutely loved them. Yes, I know this is her debut novel, but I didn't like the writing style at all. This didn't seem written by Flynn. The writing was too simple in my opinion. 
 *The pacing of the story was too fast and too slow at the same time, there's no other way I can describe it. Plus, it wasn't a page-turner to me, I had NO problem putting the book down to go to sleep, to go to class, etc. That's like a big sign for me, especially with thrillers. 
 *Another issue I had: the characters. They all felt flat to me, there was no/little background to them. I couldn't connect or feel for any of them because I literally didn't know anything about them. It was very generic like: the cop, the out-of-town detective, the weird big brother of one the girls who's been murdered, etc. 
 *Morbid and disturbing things were thrown in there just to give the story a very dark tone. I don't have a problem reading about those things but the story didn't need ALL of them together. 
 *The big reveal came at the very very end of the book and it was just rushed and I wasn't shocked because I guessed who did it a little bit more than halfway through. 
 *The reveal concerning the purpose of the teeth was good, I have to say. I was very curious about it.
