"You can't get writer's block if there's two of you writing the same thing," says Paul Stewart, author of the Wyrmeweald Trilogy. Says the books' illustrator, Chris Riddell, "It's often very unusual for a writer and an illustrator to work together. So there's something hugely comforting about having a companion, having someone traveling that journey with you." In this video, Stewart and Riddell discuss their working relationship, building fantasy around reality, and how readers will connect with the world in the Wyrmeweald series.
