A meat truck carrying illegal immigrants is intercepted at the Canadian-American border, but an unconscious woman is inadvertently left inside the truck. Two strangers waiting in separate cars impulsively smuggle her across the border - and their lives are changed irrevocably. In this complex and compelling novel, Felicity and Gus cross and re-cross borders - between countries, between past and present, and between reality and illusion - as they struggle to come to terms with borderlines of their own.
