My 6 year old (just finished Year 1) is a verocious reader. He reads for pleasure constantly. I'm told he's very good at reading for his age. However, he is also autistic and gets very scared and upset very easily, so finding things for him to read that are suitable in content, but the right reading level, is becoming more difficult. He LOVES the 13-Storey Treehouse books and has read them all multiple times - they're the scariest he can cope with (and has got upset about some things in them). He's read all the Faraway Tree book, and is reading Secret Seven at the moment. He liked the Magic Treehouse until the later ones got a bit scary for him. I'm not going near Harry Potter for the time being. He quite liked a football series (Frankie's magic football I think). Any other ideas? Ideally I'd like a series or at least a box set that he can really sink his teeth into. Thanks in advance!
