Harry Potter (raised by Special Circumstances agent Diziet Sma and sentient drone Skaffen-Amtiskaw) returns to Earth to attend Hogwarts. Sorted into Ravenclaw by a deeply offended Hat, Harry begins to jolt the Wizarding World (especially Headmaster Albus Dumbledore) with a culture shock of galactic proportions — as The Culture's own Minds try to anticipate what Harry will do next.
