They're not quite zombies. They're not quite human. And they're definitely not how Seffy Schmidt wants to spend her Tuesday. Persephone has always lived in the shadow of her practically-flawless stepsister Iris, even more so after accidentally shooting Miss Perfect in the chest during a misguided and wine-cooler-soaked turkey hunt. Now the cutting-edge treatment that saved her stepsister's life -- while somehow making her even more disgustingly amazing -- might be responsible for an outbreak that's turning the entire population of the Greater Fargo-Moorhead Area into oddly-human zombies. Armed with nothing more than her wits, a shovel, and memories of her past glory in the realm of high school science fairs, Seffy realizes that she might hold the key to saving her family, her hometown, and maybe even the world.
