The plot of The Kite Runner revolves around the protagonist's betrayal of his best friend. In a way, this betrayal drives the rest of the book and perhaps everything that precedes it. In his pre-betrayal and post-betrayal chapters, Hosseini asks some important questions. For example, do you betray someone without warning, or do small betrayals lead up to a larger one? Can you redeem yourself after you've betrayed a friend? If your father betrayed his friend are you doomed to repeat the same mistake? Can you redeem your sins and your father's at the same time? Or does redemption work like a coupon – only one per customer?
