Maguire returns with the final instalment in his transformative work, a thrilling and compulsively readable saga in which the fate of Oz is decided at last

The global bestselling series that inspired the hit musical phenomenon.

The final book in Gregory Maguire's Wicked quartet - the series that inspired the major, much-anticipated movie coming to the big screen this November.

The marvellous land of Oz is knotted with social unrest. The Emerald City is mounting an invasion of Munchkinland, Glinda is under house arrest, and the Cowardly Lion is on the run from the law. And look who's knocking at the door. It's none other than Dorothy.

Yes, that Dorothy.

Amid all this chaos, Elphaba's granddaughter has come of age. Now, Rain will take up her broom in an Oz wracked by war.
