My DS (nearly 13) is keen to read some football biographies/autobiographies. He doesn't seem interested in fiction at the moment. As long as he's reading, I'm happy to indulge him, however I think a lot of books of this nature won't be age appropriate. I don't really want him to read about affairs and scandal, more the childhood and sporting side of a footballer! He's just read one of the I,Robot ones by Peter Crouch, although I was a but worried that might not be appropriate. He says he's too old now for the Ultimate Football Heroes type books. Any recommendations?
