Author and illustrator of How to Train Your Dragon and The Wizards of Once, Cressida Cowell is also the current Waterstones Children’s Laureate. As we get lost in London's Kensington Gardens, she tells us of her passion for trees and nature, reminisces about the wild childhood trips that inspire her stories and praises the power of hope and imagination. She also shares the E.B. White quote she lives her life by and sings an anthem from one of her books! And don't miss the closing clip of a woodland walk sent in by young India and her dad.
