I am very excited to be part of World Book Day's Biggest Book Show on Earth for the second year in a row. This time I'm off to Glasgow to speak to over 2000 kids. This is the line-up: Cressida Cowell, Sir Chris Hoy, Lydia Monks, Frank Cottrell Boyce and, er, me. Gulp. Anyway, if it's anything like last year it should be a lot of fun. And quite noisy.
