Nina Spur, the prime minister's wife, was slain at a palace banquet by her own sister, Jane Spur—the emperor's forsaken concubine. Yet fate rewinds. Both sisters are reborn at the moment the Levy family's proposal arrives. Jane seizes it, vowing to marry Luke Levy, the future Prime Minister, while "gifting" Nina the chance to enter the imperial selection instead.
