Sourcery is a fantasy novel by British writer Terry Pratchett, the fifth book in his Discworld series, published in 1988.
==Premise== On the Discworld, "sourcerers"—wizards who are sources of magic, and thus immensely more powerful than normal wizards—were the main cause of the Great Mage Wars that left areas of the Disc uninhabitable. As eight is a powerful magical number on Discworld, men born as the eighth son of an eighth son are commonly wizards. Since sourcerers are born the eighth son of an eighth son of an eighth son, they are "wizards squared". To prevent the creation of sourcerers, therefore, wizards are not allowed to marry or have children.
