RED ALERT!!!!!!!!

I loved the Kite Runner and so i bought his second book- A Thousand Splendid Suns. I did not like it much. I was not able to finish it. I guess part of the fault lies with me. I could not take in the sordid details. My problem is that i like a little splash of happiness here and there. I am unable to swallow stark sadness. So i am writing here to alert people against this book ( for ppl like me).
Of course the book has its moments of truth, when you realize that the author's style still exists in the book. But i can safely say that A Thousand Splendid Suns is simply not as great as The Kite Runner.
