Sally-Anne grew up near Sheffield, in the north of England. She has worked as a writer, film and television extra and formerly as an auxiliary nurse, including a spell working in one of the last Victorian asylums in England. As a child she loved Hammer House and Tales of the Unexpected, so unsurprisingly her books lean towards the darker side. She writes female-led thrillers, inspired by the working-class women she grew up with. She has written for international print and digital publications and won an ITV initiative for her short film script, Freak Show.
