Naia Cypher is a chickenshit. At least according to her sister. Why the hell else hasn't she broken up with her boyfriend yet? Everyone knows she doesn't really like him that much. But just Naia's luck - before she gets up the guts to do it, the world ends. Now she's got to find her sister and get both of them through this shitty apocalypse where the only people who aren't trying to kill them are... probably going to kill them by accident.
