I've seen that there is already a thread on a similar theme to this today. but many of the recommendations, DD has already read!
She's read the Dick King-Smith Sophie books
Mudpuddle Farm (and now says its babyish)
Flying Fergus series
Frank Lampard football academy series
13 Storey Treehouse series
All the Barry Losers
All the Wimpy Kids
Some simpler Roald Dahls (Fantastic Mr Fox, Magic Finger) but is familiar with the stories and not bothered about reading them
The World's Worst Children 1, 2, 3
Mr Stink, Billionaire Boy
I have tried introducing the books I read at that age but she finds the either quite archaic (Mrs Pepperpot, The Family from One End Street) or too American (vocabulary - eg: Beezus and Ramona; Fudge).
She wants something more challenging that the cartoony Wimpy Kid/13 Storey Treehouse etc, but modern.
Many thanks
