It's the end of the world as she knew it, but Harper Cody feels fine.Mostly.Surviving after nuclear bombardment isn't all bad. Alarm clocks aren't a thing anymore. No one gets stuck in traffic on their way to a soul-draining nine-to-five, their food's not full of sugar and preservatives, and she got out of having to take the SATs. Constant hypervigilance, having to carry a gun everywhere she goes, and the fear that any small injury could turn fatal is a small price to pay.While Evergreen has become an oasis of sanity in a fractured world, it's not without problems. Danger is out there, watching and waiting for the perfect time to strike. Idiots and gangs, she can handle, but not everything that can kill her is so obvious.The deadliest hazards can't be seen at all-and one of them is much closer than she imagined.
