Gregory Maguire returns to the world of Wicked and 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 he power of his own? Can he liberate Princess Nastoya into a dignified death? Can he locate his supposed half-sister, Nor, last seen in shackles in the Wizard's protection? Can he survive in an Oz little improved since the death of the Wicked Witch of the West? Can he learn to fly?
