A novelist, short story and nonfiction writer, Mary Soderstrom's next book will be a novel, The Last Bridge, forthcoming from Dundurn Press in 2027. The book marks a return to fiction for her and is a sort of sequel to River Music (Cormorant Books, 2015.)  

Most of her recent work has been non-fiction however.  Dundurn published her 19th book, Before We Forget: How Remembering Will Help Us Get Through the Next 75 Years, in Spring 2026. It was preceded by Against the Seas: Saving Civilizations from Rising Waters, also from Dundurn in 2023.  Before that came Concrete: From Ancient Origins to a Problematic Future (University of Regina Press, 2020. ) That press also published her Frenemy Nations: Love and Hate between Neighbo(u)ring States in 2019.  

In 2013, Oberon Press pubished her short story collections Desire Lines, work on which was supported by a grant from the Conseil des arts et lettres du Québec.  CALQ also supported work on her  novel The Violets of Usambara (Comorant Books, 2008) which allowed her to do research in East Africa. That experience also shows up in her  book Green City: People, Nature and Urban Places (Véhicule Press.) Tanga, Tanzania, the gateway to the East Usambara mountains, is one of the 11 cities she uses in Green City as points of departure for discussing the way people have brought nature into cities over history .This travel, as well as what she did for her non-fiction book The Walkable City: From Haussmann's Boulevards to Jane Jacobs' Streets and Beyond (Véhicule Press, 2008) prompted her to consider the role of the Portuguese over the last 700 years in the European exploration of the world.  Their fascinating story lies at the heart of Making Waves (Véhicule Press, 2010.)
