Alison Knowles, from St Ives, debuted Ollie and his Super Powers at Slepe Hall earlier this month. The book tells how Ollie learns to use his emotions to overcome being bullied at school.

She has built up a reputation through her therapy room for being able to help children overcome emotional and behavioural issues. She said: There are no bad kids. All behaviour serves a purpose so we just have to understand why they are behaving the way they are. Amongst those who attended the launch were parents and teachers who had successfully applied Alis techniques. Ollie and his Super Powers is the first of five books in the series that deal with issues confronting many children of today. Ms Knowles second book, Ollie and the Golden Stripe is out now.
