Only because I am looking at books on The Book People for DD (6) and I'm not sure what age range to go for. She's reading confidently and I don't think she has trouble with the words. She's on Level 7 of ORT at school but I know that's very easy for her. But she reads the Usborne Young Readers & Puzzle Adventures and Dr Seuss, that kind of thing at home. Any ideas? I know it's not just about vocabulary but story structure etc.
