Great book!
I've read about a third of the book so far and its a very interesting story. Its quite an easy read, and it doesn't get bogged down in the details. Each chapter focuses on a different aspect of the story, so you gradually get a picture of the whole thing, rather than seeing it strictly from the beginning to the end.
You can get it for about £8 including p&p on Amazon, that's where I got it :)
