Can anyone relate the book The Kite Runner to any other book that you have read?

To answer your question I would continue the list of
themes and topics from the previous post, and then see where there are connections to
novels and a plays you have already read.  Some additional themes to
consider:

1.  redemption

2. 
bullying/ good vs. evil

3. 
friendship

4.  social class distinction -- effect on
relationship

5.  America as a land of (new)
opportunity

6.  mental/physical survival of a
crisis

7.  suicide/attempted
suicide

The list could go on, but the next step is to look
for those elements in other novels.  Just having the theme in common is a start, then
you need to determine if the authors are making a similar point.  With a little
brainstorming, you may discover that what at first seemed like a stretch, actually works
for the comparative purposes.  For example, The Great Gatsby is
about several of the topics listed above -- what can be done with the
commonalities?
