Paul Stewart and Chris Riddell are the geniuses behind the phenomenally successful The Edge Chronicles, Muddle Earth, Far-Flung Adventures and The Wyrmeweald Trilogy.

They both have hugely successful careers separately, Paul as a writer of children's books and Chris as an illustrator and cartoonist for the New Statesman and the Observer.

They both live in Brighton, where they met picking up their children from school. Together they have sold over three million books worldwide.

Alessandro Valdrighi studied in Florence and graduated with a Bachelor’s degree from prestigious Accademia delle Belle Arti as a set designer. Before going to university, when he was a child, Alessandro started drawing by copying comics and illustrations from books. He believes that’s the main reason he is able to tackle multiple styles and enjoys a challenge each respective style brings. He worked as a cartoonist, illustrator and concept artist (his favourite), with traditional and digital media. Alessandro also won a prize for his comic called Lagrimas en la lluvia, featured as the best comic book publication published in Spain.
