"Jessica Manchaky's life has been shaped by the threat of nuclear disaster. She's a child when she hears news of the Chernobyl nuclear accident, and the disappearance of Ukrainian relatives, growing up on a northern Alberta military base during the Cold War. From that moment on, all she wants is to keep danger at bay. But living in a household with a domineering and volatile mother and a rebellious older brother in isolated Cold Lake, Alberta, Jessica never feels fully safe. When she comes of age, she leaves her suffocating small town for Halifax, Nova Scotia, where she meets her future husband and eventually becomes a nuclear engineer in charge of risk assessment and management at nuclear power plants. But even as she shields the world from nuclear disaster, she is constantly facing personal tragedies -- like a strained marriage, a misogynistic workplace, and severe postpartum anxiety -- that she never quite manages to predict. When her young daughter is afflicted with a mysterious and potentially deadly illness, Jessica must learn to accept that not all risk can be managed."--Publisher.
