by Tosca Lee >> Six months after vanishing into an underground silo with 61 others, Wynter Roth and Chase Miller emerge to a nation decimated by disease. What happened while they were underground? There is no sign of Noah and the rest of the group that was supposed to greet them when they surfaced—the same people Wynter was counting on to help her locate antibiotics for her gravely ill friend, Julie. As hope fades by the hour and Wynter learns the terrible truth of the last six months, she is called upon again to help save a nation she no longer recognizes—a place so chaotic she is no longer sure it can even survive.
