To contemporaries, the Wars of the Roses were known collectively as a cousins' war. The series of dynastic conflicts that tore apart the ruling Plantagenet family in fifteenth-century England was truly a domestic drama, as fraught and intimate as any family feud before or since. As acclaimed historian Sarah Gristwood reveals in Blood Sisters , while the events of this turbulent time are usually described in terms of the male leads who fought and died seeking the throne, a handful of powerful women would prove just as decisive as their kinfolks' clashing armies. These mothers, wives, and daughters were locked in a web of loyalty and betrayal that would ultimately change the course of English history. In a captivating, multigenerational narrative, Gristwood traces the rise and rule of the seven most critical women in the wars: from Marguerite of Anjou, wife of the Lancastrian Henry VI, who steered the kingdom in her insane husband's stead; to Cecily Neville, matriarch of the rival Yorkist clan, whose son Edward IV murdered his own brother to maintain power; to Margaret Beaufort, who gave up her own claim to the throne in favor of her son, a man who would become the first of a new line of Tudor kings.
