Rhianna Pratchett would like to put certain rumors to rest for once and for all. "Since this question is doing the rounds again - No I don't intend on writing more Discworld novels, or giving anyone else permission to. They are sacred to Dad. I will be involved with spin-offs, adaptations and tie-ins, but that's it. Discworld is his legacy. I shall make my own."
