Query: I enjoyed the mix of football and mystery in this book.

I am fifteen and I have read all of Green's books more than once. I play football and I like how vividly he describes the football scenes in the book. I know I am only fifteen and some adults will think that I am just a kid and I don't know what I am talking about but, I have also read other literary works (Of Mice and Men) (Catcher in the Rye).
