This is the best book I've read in a long time. I read a lot so I think that is saying a lot.
It's a little bit Margaret Atwood's- Handmaids Tale and a little bit Philip K. Dick's- Do Androids Dream Of Electric Sheep- and a lot good.
It is so good that when I was half way done part three (the final part), I put it down for a day just so that I could make it last for longer- I don't usually do this kind of nonsense.
If you want to know what it is about google it- but I started it without knowing much about it and think that is better- as it is a slow, tantalizing reveal.
I guess they just made a movie of this book starring Keira Knightley but I don't know anything about it-
I recommend the book- it is fantastic.
Here is a great article by one of my favorite authors- Margaret Atwood- about Never Let Me Go
