Cressida Cowell on the joy of reading

Cressida Cowell (bestselling children's author of the 'How To Train Your Dragon' series) joins Sara for a natter about the joy of reading.

As an ambassador for The National Year Of Reading, Cressida is passionate about getting people reading for pleasure - especially children - and chats to Sara about the various plans in place this year to encourage more people to pick up a book, comic, graphic novel - or even listen to an audiobook.

She also takes us behind the scenes of the filming of 'How To Train Your Dragon 2' which has just started filming!
