Marianne Ratcliffe grew up in Lincolnshire. A biochemist by training, she has always found creating new worlds and interesting characters every bit as rewarding as discoveries at a laboratory bench. She had short stories published in literary magazines and was runner up in the Guildford Book Festival short story competition in 2010. In 2017, redundancy spurred her to focus on creative writing. A contract with independent UK publisher Bellows Press resulted in the publication of The Secret of Matterdale Hall, a sapphic romance/mystery set in the Victorian era, which was a finalist in the Golden Crown Literary Society Awards. Her latest novel, A Lady to Treasure, is a Regency romance inspired by the life and character of Anne Lister (aka Gentleman Jack) and was released in October 2023 and has been shortlisted for a Lambda Literary Award
Marianne lives in Cheshire with her wife and two dogs.
