Unless is the final novel by Canadian writer Carol Shields, first published by Fourth Estate, an imprint of HarperCollins in 2002. Semi-autobiographical, it was the capstone to Shields's writing career: she died shortly after its publication in 2003. The work was widely acclaimed and nominated for the Booker Prize, the Giller Prize, the Governor General's Award, the Orange Prize for Fiction, and received the Ethel Wilson Fiction Prize. In 2011, it was a finalist in the Canada Reads competition, where it was defended by actor Lorne Cardinal. Like many of her works (especially The Stone Diaries), Unless explores the extraordinary that lies within the ordinary lives of ordinary women.
