This was the first book I have sat myself down and just read without being forced to. I absolutely loved the entire thing front to back, top to bottom and left to right. The story is gripping all the way through. The characters are well fleshed out. The tension just keeps building and building. The science behind, even though it was obviously sci-fi, was still awesome. The movie was different of course but not in a bad way. However this is about the book. In my opinion the book was better by a long shot.
