Equal Rites (Discworld #3, Witches #1)
A wizard can, if he’s good enough, put flesh on his imagination.

About the Author
Terry Pratchett lives in England, an island off the coast of France, where he spends his time writing Discworld novels in accordance with the Very String Anthropic Principle, which holds that the entire Purpose of the Universe is to make possible a being that will live in England, an island off the coast of France, and spend his time writing Discworld novels. Which is exactly what he does. Which proves the whole business true. Any questions?
