In a frozen apocalyptic wasteland, Elara harbors a deadly secret: her blood runs like liquid fire, making her the world's last living heat source. Kael, the Citadel's most lethal and emotionless cryo-assassin, is sent to eliminate her. But a desperate struggle permanently binds their fates, injecting her burning blood into his icy veins. Now, a lethal curse forces them together—if they step more than ten meters apart, his system will combust and she will freeze to death. To survive, this ruthless killing machine must do the unthinkable: keep his prey dangerously close. As the freezing nights force them into intimate, skin-to-skin embraces, Kael's cold survival instinct morphs into a dark, irresistible fever. He was built to feel nothing, but as he strips away his armor to absorb her heat, he realizes he would burn the entire world down just to keep her safe. She was his target, but now, she is his only cure.
