I made the mistake of watching the film before reading this, but I'm glad I read it.
The split point of view gives you a personal view on each side of the story and you find yourselves in the heads of Nick and Amy and seeing the motives behind their actions, even when it seems crazy reading it in their mind somehow justifies it.
It kept me interested, I took a long time to read it but this was simply due to other commitments is have read it in a day if I had the time!
I'd recommend this to anyone, even if you've seen the film the book still gives you more and keeps you guessing.
