Demons possess a young man, but God empowers him to handle it, and use it for good, for Him.
Imagine a story about a young, adolescent teen who becomes demon possessed and tranforms into a hideous thing of evil. And no, this isn't, "The Exorcist," all over again. Nor is the possessed one a young woman bedbound and rapidly perishing.
Meet Jubal Kane, a young, Christian high school student who starts having some very interesting experiences as the Lord and one of his mightiest angels enlist him and his unique ability to host demonic beings in their eternal battle against Satan's legions.
In a contract as old as time itself, the demonic are allowed to exist in our world and torment mankind as long as they stay hidden in the spiritual realm. But when they decide to become flesh through the possessing of the innocent, then the Lord and his angels can take them away and imprison them forever.
Or such at least is the premise of this story as young Jubal, who we initially learn is a Walk-In, a type of human particularly adept at hosting spiritual entities, a powerful gift he uses to fight evil and reunite his mom and dad.
