Every world has its rules—even a flat one carried by four elephants riding on a giant turtle. That's why a dying wizard is searching for an eighth son of an eighth son to bestow his wizardly powers upon before meeting Death in six minutes. Unfortunately it is quickly discovered—though not quite quickly enough—that the newborn babe the wizard anoints just before bidding the Discworld adieu is, in reality,a girl!
What's done cannot be undone—despite old Granny Weatherwax's attempts to bring the child into the witchy fold—and little Eski's now a wizard, through and through. And she's destined to bring chaos and confusion to the all-male faculty of Ankh-Morpork's Unseen University...who are already fairly addled to begin with.
With their biting satire and limitless imagination, it is easy to understand why 80 million Discworld books have been sold worldwide.
