Diana Giovinazzo is the latest guest of Historical Happy Hour to discuss her latest novel, Antoinette’s Sister. As Marie Antoinette took her last breath as Queen of France in Paris, another formidable monarch—Antoinette’s dearly beloved sister, Charlotte—was hundreds of miles away, in Naples, fighting desperately to secure her release from the revolutionaries who would take her life. Little did Charlotte know, however, that her sister’s execution would change the course of history—and bring about the end of her own empire.
