A schoolgirl has written a book to explain autism

A 12-year-old girl from Crawley has been inspired by her brother to write a book about autism.

Sienna Manuel's nine-year-old brother Cruzie has autism, and she wants to protect him from being bullied.

She has written a book for other children which explains what autism is, with 23,000 copies due to be sent to every primary school in the UK.
