Sourcery. Discworld: The Unseen University Collection, Hardback

Rincewind is back in another hilarious Discworld adventure, featuring Sir Terry Pratchett's classic wit and satirical edge.

There was an eighth son of an eighth son. He was, quite naturally, a wizard. And there it should have ended. However (for reasons we'd better not go into), he had seven sons. And then he had an eighth son... a wizard squared... a source of magic... a Sourcerer. Sourcery sees the return of Rincewind and the Luggage as the Discworld faces its greatest and funniest challenge yet.

• One of our greatest fantasists and beyond a doubt the funniest
