France is mired in a losing war against England. Its people are starving. Its king is in hiding. And out of the chaos, an unlikely heroine is emerging. Reckless, steel-willed and brilliant, Joan has survived a childhood steeped in both joy and violence to claim an extraordinary - and fragile - position at the head of the French army. The battlefield and the royal court are full of dangers alike, and Joan finds herself under suspicion from all sides - as well as under threat from her own ambition.
