The Four Grannies
by Diana Wynne Jones (H. Hamilton, 1980); collected in “Freaky Families”, audiobook read by Penelope Rawlins (Clipper Audio, 2013)
An irreverent middle-grade story in the Roald Dahl mode, though with not-so-horrible characters, less revelling in the mischief making, and far less of a comeuppance. Erg’s marvellous invention and his use of it tend more towards gormlessness than a proper childhood uprising.
