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, 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.
