Regan McDonell writes dark literary fiction for adults and teens. Her 2019 White Pine Award Honour Book, Black Chuck, is a gritty, small-town coming-of-age novel that Booklist called "a superb debut," School Library Journal says is "a read that sticks in the gut," and Kirkus Reviews noted for "dynamically complex characterization and storytelling."

Regan currently lives in Toronto, where she writes, makes art and leaves love letters on subways for strangers to find. She is a proud member of The Writer's Union of Canada.

She is represented by Amy Tompkins of Transatlantic Agency.
