I’m listening to an audiobook of Gregory Maguire’s Son of a Witch, sort of a sequel to Wicked (which I haven’t read yet), on which the musical is based. He himself narrates it. I can’t recommend him as a narrator, but I’ll excuse him because I love his writing.
This starts where Wicked ends, apparently—when the witch dies. (In case you haven’t read or seen Wicked, it’s a riff on The Wizard of Oz.) Full of unexpected twists in language, character, and plot, this adult novel blends satisfyingly complex vocabulary and cultural references with the commonest of street talk. It also blends Maguire’s wild inventions with not-very-veiled references to current events.
I also loved the other book of his that I’ve read—Confessions of an Ugly Stepsister. He reimagines the story of Cinderella, placing the characters in 17th-century Holland, and turning everything upside down.
