In the Book and Sword, Louis Cha revives the legend about the great eighteenth-century Manchu Emperor Qianlong which claims that he was in fact not a Manchu but a Han Chinese as a result of a "baby swap." The novel is panoramic in scope and includes the fantastical elements for which Cha is well-known: secret societies, kungfu masters, a lost desert city guarded by wolf packs, and the mysterious Fragrant Princess.
