Since landing on planet Earth, Paul Rockett has spent much of his time reading up on the adventures of human life, while also experiencing a few of his own. In his quest to find out more about his chosen home planet, Paul has travelled, doodled, eaten a lot of food, plundered dusty libraries and gazed out of windows. Having gathered together a vast amount of fascinating data, it is now his mission to present as much as he can in interesting ways, so that any passing Martian can see how brilliant life is on Earth.
