Introduction
Moonlight has draped the ancient city of Wangchuan for three thousand years, sealing it from sunrise and from time itself. Here the Xuan, a clan whose veins run with star-forged ichor, rule over mortals who die before ever seeing a dawn.
Mu-Rong Yaoâhalf Xuan, half human, cursed with hair like molten goldâascends the obsidian throne on the same night his father chooses to die beside the human woman he could never make immortal. The lesson is carved into Yaoâs marrow: love is the one thing eternity cannot promise.
While tracing the coronation rite along the cityâs living walls, Yao finds a silver-haired boy cornered by cut-throats who harvest street children for blood sport. The boy, Ling Shuang, knows nothing of court or clanâonly hunger, and the sudden hush that falls when a single drop of his blood touches Yaoâs tongue. Yao claims him as âpersonal spirit,â a polite fiction for the truth: he has found the only warmth the moon has ever let him keep.
Their nights begin in fearâYaoâs fangs, Ling Shuangâs trembling wristâbut fear melts into ritual, ritual into devotion. Ling Shuang learns that the cold lord will break any law to see him smile; Yao discovers that a single heartbeat can eclipse an empire of stars. Yet the Xuan nobles have not forgotten the taint in their sovereignâs blood, and when Feng Li, heiress of the rival Fane-Tian, arrives with talk of alliance and betrothal, the whispers sharpen into daggers. Ling Shuang, believing himself a momentary indulgence, slips through the cityâs thousand gates and vanishes into the moonlit maze.
To retrieve the boy who taught him what mortality feels like, Yao must do what no immortal has ever daredâbreak the covenant that chains Wangchuan to endless night, and offer Ling Shuang a choice no human has ever been given: remain a single candle in the dark, or drink with him from an eternity that will never again be cold.
