Terry Pratchett has won the hearts and minds of readers around the globe with his bestselling Discworld series of novels. But what his many fans may not realize is that he has been writing nonfiction throughout his career. Some of it relates to Discworld, of course, but much of it—especially in recent years—is part of his outspoken campaigns for causes such as Alzheimer‘s research and animal rights.A Slip of the Keyboard is the first collection of Pratchett’s nonfiction work, and it brings together the finest examples of his extraordinary wit and his persuasive prose. Whether in short opinion pieces (on death and taxes), or in long essays, speeches, and interviews (covering a range of topics from mushrooms to orangutans), this collection is a fascinating look inside an extraordinary writer’s mind.
