“King of a Hidden Kingdom” by Tom Graneau is a gripping tale of cosmic rebellion, spiritual warfare, and the eternal struggle between good and evil. The story centers on Lucifer, the once-glorious archangel who, in his pride and ambition, attempted to overthrow God and seize the throne of heaven. After his failed rebellion, Lucifer and his followers are cast out of heaven, plummeting to the depths of hell in a dramatic fall, symbolizing their eternal punishment.
