Acclaimed writers like Sally Vickers and Michael Morpurgo give us things to chew over, while other Greenbelt stars of all kinds share us a taste of what's coming up, and discuss the books that make life easier to swallow.

Served up by Cole Moreton, author, broadcaster, Independent on Sunday writer and the only host in the history of Greenbelt ever to have invited fire jugglers to perform in a tent.
