Plot Summary
The conclusion to the Wicked Years saga is a dense, political, and magical exploration of the Land of Oz, now on the brink of civil war and ecological collapse. The narrative shifts focus to Rain, the granddaughter of Elphaba (the Wicked Witch of the West), as she navigates a world that has mythologized her family history.
Part I: The Green Legacy — Rain in the Kells
The story opens in the bleak, rugged landscape of the Kells, where Liir (Elphaba’s son) and his wife Candle have hidden their daughter, Rain, from the prying eyes of the Emerald City. Rain is green-skinned like her grandmother but lives in ignorance of her potent lineage. She spends her days in isolation, tasked with mundane chores, while her catatonic father, Liir, struggles with the trauma of his past. The peace is shattered when the military forces of the Emerald City, led by the Cowardly Lion (Brrr), arrive seeking the Grimmerie, the lost book of magic. Rain's existence is discovered, marking the end of her anonymity and the beginning of her transformation into a pivotal player in Oz's history.
"She was green. She was the color of the moss on the rock, the color of the scum on the pond, the color of the leaves in the canopy."
Part II: The Return of the Kansas Slayer — Dorothy’s Trial
In a shocking turn of events, Dorothy Gale returns to Oz, not as a young girl, but as an aging, bewildered woman brought back by a fluke of chaotic magic. She is immediately taken into custody. However, rather than being hailed as a hero, she becomes a political pawn. She is put on trial for the murder of the Wicked Witches of the East and West. This trial serves as a darkly comic and satirical critique of celebrity and justice. Rain, now venturing out into the wider world, crosses paths with this legendary figure, realizing that the "monster" who killed her grandmother is merely a confused human woman full of regrets.
Part III: The Clockwork Dragon — Brrr’s Final Gambit
Brrr, the Cowardly Lion and current Prime Minister, is revealed to be a complex bureaucrat trying to maintain order under the tyranny of Emperor Shell (Elphaba’s younger brother). Brrr is tasked with securing the loyalty of the Munchkinlanders and finding the Grimmerie. He is haunted by his own cowardice and the mechanics of the Clock of the Time Dragon. As his health fails and his political power wanes, Brrr attempts to manipulate the board one last time, seeking redemption not through bravery, but through the preservation of history, ultimately realizing that he has been a tool of oppression for too long.
Part IV: The Siege of the Emerald City — Glinda’s Resistance
Glinda, the former Good Witch, is now under house arrest, her power largely symbolic. However, she remains a master manipulator. As Emperor Shell prepares for a total war against the rebellious Munchkinlanders, Glinda secretly orchestrates a resistance. She weaponizes her social influence and her knowledge of the Grimmerie to aid Rain. The narrative exposes the hollowness of the Emerald City's grandeur, showing it as a crumbling empire built on propaganda. Glinda and Rain share a poignant connection, bridging the gap between the "Good" and "Wicked" archetypes.
Part V: The Battle for Kiamo Ko — The End of Magic
The climax converges on Kiamo Ko, Elphaba's old castle. Armies from the Emerald City, rebellious factions, and the sentient Clock of the Time Dragon collide. Rain embraces her heritage, taking up her grandmother’s broom and the Grimmerie. In a devastating aerial and magical assault, the landscape of Oz is irrevocably changed. The battle is less about victory and more about survival and the cost of war. Rain uses the Grimmerie not to conquer, but to perform a final act of magic that separates the mundane world from the magical, effectively sealing Oz away from further external contamination.
Part VI: Departure — The Flight Beyond the Rainbow
In the aftermath, the surviving characters face their ends or new beginnings. Dorothy finds a way home, finally laying her guilt to rest. The Grimmerie is taken beyond the reach of those who would abuse it. Rain, having accepted her green skin and her destiny, chooses a path of solitude and freedom, flying off into the unknown. The book concludes with the sense that the age of witches and wizards has passed, leaving Oz to heal from its wounds naturally. The "Wicked" legacy is redeemed not through dominance, but through the courage to let go of power.
"The book was gone. The witch was gone. The green was gone. But the story remained."
