Gone Girl

I feel like this book leads you in a very specific direction to make you truly believe the whole thing and then, by half of the story, its meaning totally changes and starts to get really exciting. I wasn't loving it at first but I think it gets quite thrilling towards the end.
This is the most accurate - and extreme - representation of a marriage gone wrong. Also, one of the main characters of this book is pretty strong, which I loved.
Film is pretty good as well, it sticks completely to the story from the book.
