dd (7) is a very fluent reader, but we've got to a bit of an awkward stage, where she's gone beyond the books in the 'young fiction' part of the library, but the subject matter of a lot of the books for older kids just goes way over her head.
She does, however, love illustrations (especially really detailed ones), and I'm looking for some children's novels which she can get her teeth into, but which have lots of pictures as well. She loved the Far-Flung Adventures and Ottoline books and has just read Ian Beck's Tom Trueheart, so books in a similar vein would be great. Her elder brothers are demolishing the Edge Chronicles at the moment, but I think they're a bit too 'boyish' for her at the moment
