British fantasy author Terry Pratchett dies at age 66

Terry Pratchett, author of more than 70 books including the popular Discworld fantasy series, has died at his home, his publisher said Thursday.

Pratchett announced in 2007 that he had early-onset Alzheimer’s disease, which he called an “embuggerance.” He died with his family and beloved cat with him.

Pratchett “enriched the planet like few before him,” said Publishers Transworld managing director Larry Finlay. “All who read him know, Discworld was his vehicle to satirize this world: he did so brilliantly, with great skill, enormous humor and constant invention.”

He was deemed the UK’s bestselling author of the 1990s and has sold more than 85 million books worldwide, most of them in the Discworld series.

The 40 Discworld novels depict a mythical world set on a flat disc balanced on the backs of four elephants standing on the back of a giant turtle. The fanciful stories feature wizards, witches and trolls.

Pratchett is survived by his wife Lyn and their daughter Rhianna.
