Ride the River (Hardcover, Turtleback School & Library ed.)

No matter that Echo Sackett was young, and a woman, and had never been far from the valley. She was still a Sackett -- sharp and smart and a better hunter than most of the men she knew. Like her bold ancestors, Echo couldn't ignore a challenge. A sure hand with a horse, a dead shot with a rifle, and fast with her wits, Echo traveled to the mountains of Tennessee, coming up against ruthless killers who's stop at nothing to cheat her out of her inheritance. There she'd prove once and for all the she could ride the river with the best.
