Su Qian, the eldest princess of Qianluo in the Su Kingdom, is breathtakingly beautiful, shrewd, and powerful enough to command half the realm. Yet she is a frail young woman, poisoned by a strange toxin and not long for this world. Shangguan Mo, crown prince of the Western Moon Kingdom, is elegant and refined, perched high above the world and revered by all as the First Young Master. But when he falls in love with her, he sheds his noble airs and schemes in the shadows without hesitation. The various kingdoms raise armies, plot against one another, and fight for dominion. The Su Kingdom and the Western Moon Kingdom, sworn enemies, are especially unable to escape their entanglement. In these turbulent times, love is the most extravagant luxury of all. Who holds the world in their grasp? Who plots behind the scenes? Who turns the tides? And who struggles simply to survive? With this life not yet finished, she will use every ounce of her cunning to command the armies of a chaotic age and seek peace for all.
