"Six years after a global pandemic wiped out most of the planet's population, the survivors are rebuilding the country, split between self-governing cities, hippie communes and wasteland gangs. Krista, Moira, Rob and Sunny are brought together by circumstance, and their lives begin to twine together. But when reports of another outbreak throw the fragile society into panic, the friends are forced to finally face everything that came before - and everything they still stand to lose. Because sometimes having one person is enough to keep the world going."-- Publisher description.
