The world is dead. The plague left behind monsters of steel and flesh, and crowned one of them king. He is the Cybernetic King. Immortal. Cursed. A warlord of metal and decay, ruling his empire with an iron fist and an obsession that cannot die. When Aria Vale, a scavenger fighting to survive in the ruins, is captured by him, she expects death. Instead, he spares her… because her blood is unlike any other. It resists the nanovirus that keeps him alive. To him, she is not a prisoner, she is the key. But as Aria resists his control, she is drawn into a world of dark desire and terrifying power. The King promises her everything, luxury, protection, a place at his side, while keeping her locked inside his fortress, body and soul. The more she defies him, the more dangerous his obsession grows. Soon, she must make an impossible choice: betray him and side with humanity, or surrender to the monster who would burn the world to keep her. One thing is certain. She can save him… or destroy him. And either way, he will never let her go.
