Charles Towne (Keepers of the Ring Book Five)

All her life, Rachelle Bailie believed that her father was an English clergyman killed in an Indian attack. But her mother now confesses that Rachelle’s father, Mojag Bailie, still lives — and that Indian blood courses through his veins.
In her quest to locate her father, Rachelle boards a ship bound for Boston. Then the ship is attacked by the pirate Bettencourt.
Finding herself face-to-face with the notorious renegade, Rachelle does the unthinkable … and finds herself caught up in an adventure beyond her wildest imagining.
