Six months after vanishing into an underground silo with 60 others, Wynter and Chase emerge to find the area abandoned. No sign of those who were supposed to greet them when they emerged—the same people Wynter was counting on to help locate the IV antibiotics her gravely ill friend, Julie, needs in order to live.
As the clock ticks down on Julie’s life, Wynter and Chase embark on a desperate search for medicine and answers. But what they find is not a nation on the cusp of recovery, but one decimated by disease. With food and water in limited supply and their own survival in question, they come face-to-face with a society radically changed by global pandemic, where communities scrabble to survive and cities are war zones. As Wynter learns the terrible truth of the last six months, she is called upon once again to help save the nation she no longer recognizes—a place so dark she’s no longer sure it can even survive.
