My 11 year old nephew is an avid reader. 2 Christmases ago, I bought him a book called Fantasy Football by Mike Lupica. He loves his sports as well. He's on his 4 book by him and has read several by Tim Green as well. All sports related, so it's a great tie in for both his "loves." Today, he brought the 4th Mike Lupica book that he was so excited to show me. He got it at school from the Scholastic book fair.
It's so much fun seeing him get excited about reading an actual paper book rather than his electronics!
