Diamond released her first novel, Mona's Dance, in 1989, followed by short story collections Snakebite in 1989 and Evil Eye in 1991. Her narrative style has been called "distinctive" as it "blur[s] ... realism and surrealism";[1] and her fiction also tends to "feature female characters burdened by painful relationships."[1]Evil Eye won the 1994 Hugh MacLennan Prize for Fiction.[2] In 2000, Diamond released Dead White Males,[5] followed by Static Control in 2006.[1]
In 2006, Diamond published a memoir, My Cold War, where she claims to be a victim of secret mind-control experiments, allegedly sponsored by the American CIA.[1] The book was republished under the title A Certain Girl in 2011.[1]
