Years after his bloody rise to fame, a crippled former assassin turned corporate official is dragged back into violent intrigue when an exiled god from a parallel world appears on Earth, exposing a conspiracy to unleash a catastrophic plague for profit and control. As political and divine powers collide across two realities, he battles executives, zealots, and his own fractured identity to protect his family and prevent genocide, in a brutal exploration of power, responsibility, and redemption.
