Savage Horizons (The Blue Hawk Saga #1)

An orphaned half-blood man named Blue Hawk is adopted by a white family and renamed Caleb Sax. Caleb struggles to let go of the only habits and culture he's ever known - that of the Cheyenne - and gradually learns to live among the whites, but not without great difficulty and prejudice against him in the white world. Through it all he never stops wearing a blue quill necklace that belonged to his Indian mother, a part of his past that will always remind him of his true blood.

Besides Tom and Cora Sax, the white man and woman who love Caleb like their own son, someone else shows Caleb true, loyal love. It is Tom and Cora's daughter, Sarah. Sarah and Caleb fall in love, instigating years of struggling to stay together against tremendous odds. Sarah discovers Tom Sax is not her real father, and she is stolen away in marriage to a white man she does not love. Devastated, she is led to believe Caleb is dead. Caleb spends years searching for her, and when he finds her at last, a dynasty is born from their blood.
