A book review by Elisabeth Carey
A dying wizard makes his way to a blacksmith's home, where the smith, an eighth son, is awaiting the birth of his eighth son. The wizard bequeaths his magic, and his wizard's staff, to the just-being-born eighth son.
Except that this eighth son is a daughter, and this fact is discovered just barely too late.
When Eskarina's unfortunate magic begins to manifest itself, Granny Weatherwax attempts to maintain the proprieties by training her as a witch. She has incomplete success with this project, and is eventually forced to risk exposing the rest of the world to Eskarina by taking her to Unseen University. Great fun.
