The Book and the Sword, Jin Yong's debut wuxia novel, is set during the reign of the Qianlong Emperor of the Qing Dynasty. It follows Chen Jialuo, the scholarly leader of the Red Flower Society, a secret brotherhood sworn to overthrow Manchu rule. When the society discovers that Qianlong is secretly a Han Chinese—Chen's own long-lost brother—they attempt to persuade him to restore Chinese governance. Torn between brotherhood, patriotism, and imperial power, the emperor ultimately betrays their trust. Interwoven with the tragic love story of Princess Fragrance and sweeping adventures across the empire, the novel explores loyalty, sacrifice, and the cost of revolution.
