Paul's books cover a wide range of subjects, from whether the Romans ate crisps to how to build the world's best skatepark, but he writes mostly about sport.

Whether you are interested in swimming or cycling, snowboarding, surfing or another sport, Paul has probably written something that will inspire you to get out and give it a try.

Paul writes in a shack by the beach, which he shares with his one-eyed surf dog, Daisy.

Dave Smith is an illustrator (or "Professional Doodler" to his friends) and enjoys drawing things that make him, and other people, laugh. He also plays the drums, strums a guitar (pretty badly), and has an unhealthy enthusiasm for elderly German campervans. When colouring-in he never goes over the lines. Well, almost never...He lives and works in Devon, with his two children and a nutty Spaniel.
