White Clouds On The Horizon by Deborah Tadema
Lucas Sievers is a trapper and as wild as the Indians. He drifts between cultures. Many men fear him. Yet, he is gentle and will fight to the death for the one woman who can tame him
Winda escapes slavery only to face Pakwis, the Ojibwa chief, again when she needs his help. She fears that he will want his slave back, and she will lose the man she has fallen in love with. But without his help they could be attacked by the Americans who are receiving shipments of a newer and more powerful rifle than the Brown Bess that the people in Upper Canada are using.
