Lisbet McTavish embarks on a heroic quest in 1830. She is a lonely, imaginative, and impulsive child who can ride, swim, shoot, and hunt like a boy. Lisbet is just fourteen, but already has the valorous heart of a falcon. She travels with her father from the foothills of West Virginia to Pittsburgh. There they catch a keelboat that takes them to Fort Gibson, Oklahoma.
Lisbet has a hidden heritage and links to the spirit world of our Native Americans. She wants to find friends who will accept her, but her real quest is to find the silver mustang she has ridden so many times in her medicine dreams.
As she meets slave catchers, thieves, river pirates, gamblers, and an epidemic, will her unusual heritage and upbringing help her survive on the bloody frontier? Will she find any true friends? Will her dreams lead her to her silver mustang?
