Book suggestions to help explain Aspergers to a 10 year old girl

Hello everyone. My 10 year old daughter has recently been diagnosed with high functioning Aspergers and I am looking for a book to help explain it to her. However all the ones I can find seem to be based on boys (e.g. 'all cats have aspergers' ), for teenagers, or written by Americans so the school information is different. Can anyone recommend a good book to read with her? Thanks very much.
