A little knowledge is a dangerous thing, but it’s not half so bad as a lot of ignorance. Everyone knows there’s no such thing as a female wizard. So when a dying wizard accidentally passes on his staff of power to an eighth daughter of an eighth son, the exclusively masculine world of wizarding is thrown into a tailspin. Eskarina isn’t afraid of male critics and she isn’t going to relinquish this unexpected gift. With a little hocus pocus from Granny Weatherwax, the Discworld’s most infamous witch (an old crone who has plenty of experience ignoring the status quo), Esk infiltrates the magical Unseen University and befriends another apprentice, a wizard named Simon. But power is unpredictable, and these bright young students soon find themselves in a whole new dimension of trouble. . . .
