Lyon, the youngest pup of the far-north wolf clan, ventures alone into the eternal night city to slay Oliver, the vampire lord. He craves victory to prove his worth to his pack.
But his assassination attempt unravels two buried truths: a life-saving debt the vampire did for him ten years ago, and a century of fake blood feuds fabricated by old-school conservatives to keep the two races divided.
To make amends and rewrite fate, Oliver risks everything. He takes deadly poison and swears a sacred oath, sharing equal ruling power with his would-be killer.
When shadow demons invade the realm and traitorous factions stage a coup, the wolf and vampire stand side by side. They bind their races with blood, defend the city from collapse, and shatter the thousand-year shackles dividing their kind.
Finally, they slay the shadow demon emperor. After endless darkness, the first ray of sunlight touches the land — birthing a brand-new era of joint rule.
