Apocalypse NOPE!!

Creepy. Grudge Girl. Bigfoot. Also known as Ivy-Jean, a tall, gloomy teenager whose only friends are wild spiders. One day she commits a federal crime by opening her neighbor's mail and summons War, one of the Four Horsepeople. Suddenly it's her job to bring about the apocalypse.
In fact, she has no choice. End humanity, or the one person who cares about her will be sent to hell. To protect her mother, Ivy-Jean agrees to give the apocalypse her best shot. But plans unravel at horrifying speed when Pestilence usurps the high school debate team, War infiltrates the D&D club, Famine aspires to become a world-famous chef, and Death finds love for life in an unlikely place. If Ivy-Jean doesn't correct their course, she'll lose the horsepeople to the forces of good forever.
