DD (6) has thankfully whizzed through the rainbow fairies stage in a matter of weeks (phew!) and is ready for something a bit more challenging. She doesn't like Horrid Henry (probably because both her brothers loved them ...), isn't wildly keen on Roald Dahl or the Worst Witch, has already read a lot of Dick King-Smith and I can't stand Enid Blyton. A lot of the books we have for this sort of stage are quite boy-ish - and she's a very girly girl. Any recommendations for books which will be an appropriate level of difficulty (free reader at school) and also appropriate in content for a (young - as in emotionally young) 6 year old?
thanks
