Born in Trieste, Gunn came to Canada when she was eleven. She is the author of two novels (Tracing Iris and Thrice Upon a Time), two short story collections (Hungers and On The Road), one poetry collection (Mating in Captivity), and an opera libretto -- Alternate Visions (music by John Oliver). As well, she has translated from Italian two collections of poems (Devour Me Too and Traveling in the Gait of a Fox) by renowned Italian author, Dacia Maraini. Gunn's novel Tracing Iris has been optioned for a film, and her work has been published widely in literary magazines, anthologies and text books, and been translated into Italian and Chinese. She is Treasurer of The Writers Union of Canada, and a member of The Literary Translators Association of Canada, and Pen International.
"Gunn's wonderfully quirky and rigorous imagination, her unquenchable curiosity, her poet-passion for the plasticity of language, her knack for twinning grit and intelligence, are alive and kicking in Hungers..."
