A breakout novel for a young writer whose last book was shortlisted for the Trillium Prize alongside Anne Michaels and Margaret Atwood, and whom the Toronto Star called a "force of nature." Hazel Hayes is a graduate student living in New York City when she learns that she is pregnant from an ill-advised affair with her married professor. More worrisome than the shock of this discovery is the apocalyptically bad timing: random but deadly attacks, all by women with light hair, have begun terrorizing the city's inhabitants. As the days pass, it becomes clear that the attacks are symptoms of a strange contagion that is transforming blondes from all walks of life--whether CEOs, flight attendants, students, accountants, television personalities, or academics--into rabid killers. Hazel--confused, desperate, almost penniless and soon visibly pregnant--flees the city and sets out to cross the border into Canada where she will find the one woman who just might be able to help her in a world gone awry.
