I read The Kite Runner & A Thousand Splendid Suns by Khaled Hosseini back to back. I heard some people mention that they didn't think A Thousand Splendid Suns was as good as The Kite Runner.
I couldn't disagree more. Not only are they both superbly written, but I believe they give a unique insight into the recent history of Afghanistan.
If you've been putting off reading these books (for whatever reason!), please buy yourself a copy and tucked in.
