At a normal walking pace, it would take around 20 minutes to walk around the 27-acre square field. If the 27 acres are in any shape more rectangular or irregular than a square, it will take longer to walk around.
Hosseni wrote The Kite Runner to show the world the way that common issues of identity, assimilation and power are carried out in his culture in Afghanistan. He spends a great deal of time developing Amir and showing how he comes to a self-identity by the end of the book.
So, this is a catchy title. That's probably the first thing you notice about it. The second thing you might notice about the title is that Hosseini didn't name the book The Kite FIGHTER. Which means Hosseini didn't title his novel, weirdly enough, after his main character.
