My protagonist is Nicola (Nicholaa) de la Haye: the woman who saved England.

Nicola isn’t a creation of legend or folklore. She was real — a formidable 12th- and 13th-century noblewoman who defied the expectations of her age. She inherited power in her own right, commanded a castle garrison, and twice (at least) defended Lincoln Castle from siege.

Most famously, in 1217, when England teetered on the edge of conquest by Prince Louis of France, Nicola — then nearly seventy years old — refused to surrender her castle. She held the fortress until William Marshal’s army turned the tide in what chroniclers called the Battle of Lincoln Fair (or the Second Battle of Lincoln). Without her, England’s story might have ended very differently.
