Pritchett has found a way to make witches even more "metal" than they were in the previous books. The portrayal of them riding the brooms forming a wing is absolutely badass. The story starts with an inevitability of an old witch losing and unfolds into an adventure planned out by her in quite some details.

Diverse set of characters, plot twists and wit. My favorite quote is exploring the perception of justice and the willingness to act upon it:

“Let’s throw her off the tower,” said Magrat.

“All right,” said Nanny. “Do it, then.”

Magrat hesitated. “Well,” she said, “when I said let’s throw her off the tower, I didn’t mean me personally throwing her off, I meant that if there was any justice she ought to be thrown off—”

“Then I shouldn’t say any more on that score, if I was you,” said Nanny, kneeling carefully on the crunching shards.
