Based on historical fact, this exciting tale is set on the Missouri frontier during the War of 1812. Millie's family and the other families living at Fort Cooper face certain defeat when they are besieged by a coalition of Indian nations allied to the British. Millie, who is only twelve years old, volunteers to ride to nearby Fort Hempstead for reinforcements. Her desperate journey turns the tide of battle. Harrowing events, dramatic dialogue, and an unlikely heroine bring this fast-paced story to life. Ronald Kil's detailed illustrations add to the authenticity of an action-packed story that teaches the responsibility of everyone, even the youngest citizens, to the larger community.
