Jared Greene will either lead millions to Jesus Christ, or to their slaughter. That much is certain. The deciding factor, the element that will determine humanity's future, is free will.
In an attempt to influence his destiny, a powerful demon-a Succubus-is summoned to seduce Jared and manipulate his choices. He succumbs to the clutches of the demon, and while under her spell, Jared soon becomes enticed by the idea of having ultimate power.
As time runs out, Jared is forced to choose between good or evil, a decision that will seal the fates for millions of people around the world.

PLEASE NOTE: The Succubus is the sequel to The Incubus, and you should rather read The Incubus first if you haven't done so already.
