Having read the other reviews, I have to assume that the book gets better towards the end. I wouldn't know, because I found it unreadable, and gave up after the first 100-150 pages. The characters just didn't seem real to me, and nor did the emotions of the main character.
It wasn't the type of book that you could get lost in, and everything just seemed fake. I seemed to be repeatedly reminded that I was reading a book, and that it definately wasn't real. I haven't read the other Tony Parsons books, so I can't compare this with them, but I was definately disappointed by it.
