I'm trying to find the title of a novel

Hello everyone, I'm trying to find the title of a novel I've been wanting to read. It's a bestselling book that tells the story of a boy from Afghanistan and his journey to seek redemption for past mistakes. The story spans several decades and explores themes of friendship, betrayal, guilt, and redemption. I think the title might be something like 'The Kite Runner' or something similar, but I'm not sure. Does anyone know the title of this book? Thank you for your help!
