Chatterbooks
The award winning scheme Chatterbooks is a reading group programme for children aged four to twelve which is all about encouraging a love and enjoyment of reading. It's a national network of reading groups for children, coordinated by The Reading Agency. Chatterbooks groups are run in libraries and schools, and all sorts of places where children do fun and creative activities.
Your local library or school will be able to tell you what groups are available in your area.
