Mary Averling grew up across England and Canada, never far from the woods. She has degrees from the University of Victoria and Lucy Cavendish College, Cambridge. Her debut, The Curse of Eelgrass Bog, was a Bram Stoker Award Finalist, a Junior Library Gold Standard Selection, an ALA Rainbow List Pick, and one of BookPage's Top 10 Books of 2024. Since she can't stay away from libraries for very long, she is currently working toward her PhD in Ontario, where she lives surrounded by all the magical, spooky, heartfelt books she can find.

She is represented by Kelly Sonnack at the Andrea Brown Literary Agency.
