Just a word of advice. Do not take this book to the park to read while your children chase others about on the playground.
You just may end up sobbing on the wooden bench in the midst of shiny happy little people. The stranger next to you on the park bench may feel increasingly uneasy with the intensity of tears and move away from the obviously emotionally disturbed person you've become.
It's probably best if you read Kite Runner next to a full box of tissues in a room all by yourself.
