Katherine Louise Mosse is a British novelist, non-fiction and short story writer and broadcaster. Born in Chichester, West Sussex in 1961, she has established herself as a significant figure in contemporary literature. Mosse is best known for her 2005 novel Labyrinth, which has been translated into more than 37 languages, bringing her work to a global audience. Beyond her own writing, she has made an important contribution to the literary world through her advocacy for women writers. In 1996, Mosse co-founded an annual award for the best UK-published English-language novel by a woman. This award has since become known as the Women's Prize for Fiction and remains one of the most prestigious literary honors in the UK. In 2024, a sister award, The Women's Prize for Nonfiction, was established, further expanding her legacy of supporting women's voices in literature.
