Resilient Queen Joanna of Naples (1326–1382) weathered overwhelming political challenges, financial ruin and a papal-run murder trial for the death of her Hungarian husband—all by age 22. Veteran author Goldstone (Four Queens
) expertly describes bloodthirsty 14th-century politics and the complex family entanglements that encouraged siblings and cousins to clash over kingdoms like toddlers brawling over toys. Adding to the fray was Joanna's military support for “anti-pope” Clement VII against Pope Urban VI, ultimately helping create the Great Schism. Although primarily set in pre-Renaissance Naples, familiar contemporaries such as England's Black Prince and St. Catherine of Siena appear. Joanna repeatedly suffered violently jealous consorts, intrusive popes and envious relatives. Goldstone effectively proves Joanna's innate leadership through the queen's mastery of complex legal arguments and her formidable resilience through four husbands and relentless challenges to her royal status. Packed with action and effortless to read, Goldstone's account will satisfy scholars and entertain book clubs with a heroine who had persistence and unbounded dedication to her realm. 16 pages of color illus; 3 maps.
