Cora Reims lived the isolated life of a simple farm girl until one fateful summer day, prophetic visions brought her a visitor made of pure light... an angel. In the aftermath, Cora gave birth to a child, a Nephilim: the offspring of an angel and a human woman, seemingly imbued with evil itself. 17 years later, that child's cherubic appearance can no longer hide his monstrous nature. Frogs boil in their skins as he passes. Crops rot. The townspeople live in fear, knowing that atrocities follow closely behind him. Now, on the eve of his 18th birthday, Cora receives a new vision... Heaven itself has called upon her to destroy the abomination born of her own flesh and blood.
