On Day 56 of the pandemic called BluStar, sixteen-year-old Nadia's mother dies, leaving her responsible for her younger brother Rabbit. They secretly received antivirus vaccines from their uncle, but most people weren't as lucky. Their deceased father taught them to adapt and survive whatever comes their way. That's their plan as they trek from Seattle to their grandfather's survivalist compound in West Virginia. Using practical survival techniques, they make their way through a world of death and destruction until they encounter an injured dog; Zack, a street kid from Los Angeles; and other survivors who are seldom what they seem. Illness, infections, fatigue, and meager supplies have become a way of life. Still, it will be worth it once they arrive at the designated place on the map they have memorized. But what if no one is there to meet them?
