Want to know why your socks go missing? Can't find your schoolbooks? Wonder why everything ends up under your bed? Blame Paddy McCann, your times-forty great-grandson who's researching his ancestors - - You Paddy McCann is in trouble. Not only does he have the most cantankerous teacher in Castlemaine College picking on him, but also his research project (a lost dog from 2008AD) has just run away and lost himself in 3005AD. Paddy needs to prove that he is 'ethical and responsible' before he is allowed to visit the 21st century, but things keep getting in the way. Things like jellyfish, skunks, lost socks and bossy Erian Tovasser. When finally he arrives, and just as he's learning to master the problems of wheels (on bikes, cars, skateboards and trains), he and all his other classmates are recalled to school... but not before Paddy lands himself in dire strife... more than even he could imagine. Paddy's got himself into a disaster zone in the 24th century, his teachers are furious with him, the world is suddenly in crisis, but the man whose life he's saved sees it very differently. So is Paddy McCann the worst troublemaker of the century? Or has he just saved the world?
