An interesting thing happens when a man is defeated in combat by a woman. He tells nobody. Seventeen-year-old Cass expects to follow in her sister's footsteps: marriage, children, a quiet life. But on the day of her sister's wedding, a chance encounter with a fierce and beautiful leather-clad woman leads her to the Sisters of Sword and Shadow. Joining a group of female knights training in secret to right the wrongs of men, Cass enters a world of ancient feuds, glorious battles, and dangerous men. And soon, she discovers that she holds a power that could change not only her own fate but that of her entire sisterhood
