Ten years after the publication of "Wicked", bestselling novelist Gregory Maguire returns to the land of Oz to follow the story of Liir, the adolescent boy left hiding in the shadows of the castle when Dorothy did in the Witch. A decade after the Witch has melted away, the young man Liir is discovered bruised, comatose, and left for dead in a gully. Shattered in spirit as well as in form, he is tended by the mysterious Candle, a foundling in her own right, until failed campaigns of his childhood bear late, unexpected fruit. Liir is only one part of the world that Elphaba left behind. As a boy hardly in his teens, he is asked to help the needy in ways in which he may be unskilled. Is he Elphaba's son? Has his power of his own? In "Son of a Witch", Gregory Maguire suggests that the magic we locate in distant, improbable places like Oz is no greater than the magic inherent in any hard life lived fully, son of a witch or no.
