It is 2034, and a comet strike has done what epidemiologists always warned about: unleashed a virus that has hollowed out civilization in Silver City, a small Midwestern town, turning nearly everyone into something feral and violent. Lana regains consciousness in the middle of the collapse, already feeling the infection beginning to take hold.
Her only chance at survival comes in the form of Amy — an eight-year-old autistic girl with strange and unexplained abilities whose presence seems to slow the virus's progress in Lana. Together, the two must navigate past infected crowds, military patrols, and worse, fighting not just for their own lives but for whatever comes after — for a future neither of them can see clearly yet.
