Jack Booker, a gangster from Victorian's Underworld, finds himself thrust onto the world stage as a prophesied savior when he is used by a goddess to further her rebellion against the imperial regime. Hunted by the Primal Empire and struggling to accept his new role, Jack must decide if he will accept the power given to him or discard it to save himself, all while trying to free his people from oppression. But the situation is more desperate than he realizes. The Empire musters an overwhelming force, allies harbor festering grievances, and sinister gods seek to sabotage his efforts every step of the way. The greatest danger, however, may lie within - in the treachery of his own soul.
