13 DEMONS DEAD

This teenage girl has just one year to defeat thirteen invisible demons...without flunking out of high school!
Fourteen-year-old Everly "Ev" Espada is walking home one night when she spots her favorite teacher, Father Serrano, suspended in midair, choking and being ripped apart by something she can't see. Acting on pure instinct, Ev swings a nearby pipe and shatters the illusion, exposing a monstrous demon in the middle of her school. With one lucky shot, the creature is dead. And so is Ev's normal life.
By killing one of Earth's Thirteen Hidden Demons, Ev has unknowingly triggered an ancient covenant. She's been marked as the latest demon hunter, and the remaining twelve demons are already coming for her. The rules are simple and merciless: slay all thirteen within one year... or they will return more powerful, more vicious, and utterly unstoppable.
This high-octane, black-and-white, manga-inspired graphic novel comes from writer Adam Tierney (Teen Titans Go!) and artist Saspy, delivering brutal action, emotional stakes, and cinematic monster-slaying on every page.
