When Petra Smith joins Clandon Comprehensive, Terry Bull finds there is a real mystery about her. She is too perfect at everything, is oddly clueless about human nature, and her house is devoid of real human habitation, including parents.
Eventually Terry discovers Petra is from a dying planet. Her people sent her to Earth to see if it would make a suitable home for them. But after finding out – the hard way – that her people have no natural immunity to the common cold, Petra will be reporting to them that it is not.
