Rhianna Pratchett is a freelance computer games scriptwriter, narrative designer and former journalist who writes regularly for the PC games magazine PC Zone and the The Guardian newspaper. She is the daughter of Terry Pratchett, the best-selling fantasy and children's fiction author, famous for his Discworld series of novels.
Pratchett wrote for "Mirror's Edge", but was brought in late in the development process, and limited in what she could do. Her ideas for a story became manifest in the Mirror's Edge (comic). She will not return as a writer for "Mirror's Edge Catalyst".
