Prime Cassie (Sunfire, #14) By Vivian Schurfranz –

Her love was as wild and untameable as the frontier itself Her brave heart is torn between two worlds.Ever since blonde Cassie Stevens was captured by the Indians at the age of four she has loved her Iroquois family, and at fifteen she can shoot and ride as well as any warrior Then her world is destroyed when passion drives her from the only home she knows Where does Cassie truly belong In the arms of the handsome and adventurous fur trapper Joshua, or in the town where she was born, with Ben who mistrusts her Indian spirit
