Ethan Cross awakens after death inside Azrael Nocthar, a twelve-foot-tall Giant Demon Prince and heir to the Demon Empire. The original Azrael still lives within the same body, leaving two souls with opposing personalities, memories, and desires forced to share one destiny. With Lucien Astor investigating, rival nobles and Azrael’s half-brother Draven circling the throne, and humans preparing for war, Ethan and Azrael must learn to cooperate. Their uneasy journey brings them into contact with demon nobles, a human mage who can perceive both souls, and a human adventurer who may become an ally. As conspiracies, monsters, ancient magic, and the truth behind Ethan’s reincarnation threaten Eldoria, they uncover the Giant bloodline’s purpose as guardians of a boundary between worlds. Their greatest challenge is becoming partners without losing themselves, while deciding whether humans and demons can share one future.
