Haven't read the Kite runner but am thinking of reading it. I have read A thousand Splendid suns by the same author and that was an emotional exprience. If I think about it for too long I get teary eyed. I remember reading it in the library at uni and crying in public.
I've actually seen the film version of the Kite Runner. I enjoyed it but the rape scene was way too much. I wanted to turn the film off after that but stayed with it.
I think I will go and buy it now as it seems to have good reviews. I hope it will be as good as a thousand splendid suns.
