Tiffany Aching takes over Granny’s steading as well as keeping her own. It’s exhausting, flying back and forth between the Chalk and Lancre. But the job of a witch is to take care of her people, and how can she do that on a part time basis? Clearly she can’t.
Not much of a spoiler, the set up is really obvious.
And the best woman for the job is… a man?
I feel very odd about that. Decades ago, Eskarina Smith was a woman becoming a wizard (a man’s job), so it seems logical to come in a full circle and have a man become a witch (a woman’s job).
