My 13 year old really enjoyed reading Bob No Ordinary Cat, which is an edited version of A Street Cat Named Bob. Bag language and drug references removed. We also have a youth version of The Martian. Can anyone recommend any other youth versions of books? He'd quite like sports (football) biographies or similar but I don't really want him reading about their infidelity and addictions! He's too old now to want to read the child orientated sports books, so we're looking for something inbetween. I don't even know the correct terminology to search. 'Youth versions of....' doesn't result in much, but they exist!
