Publisher's Synopsis
Joy has no one. She spends her days working the graveyard shift at a grocery store outside Boston and nursing an addiction to cough syrup, an attempt to suppress her troubled past. But when a sickness that begins with memory loss and ends with death sweeps the country, Joy, for the first time in her life, seems to have an advantage: she is immune. When Joy's immunity gains her admittance to a hospital in rural Kansas, she sees a chance to escape her bleak existence. There she submits to peculiar treatments and follows seemingly arbitrary rules, forming cautious bonds with other patients - including her roommate, whom she turns to in the night for comfort, and twin boys who are digging a secret tunnel. As winter descends, the hospital's fragile order breaks down and Joy breaks free, embarking on a journey from Kansas to Florida, where she believes she can find her birth mother, the woman who abandoned her as a child.
