A Thousand Winds That Blow — Nancy Morse

Wild Wind Series, Book 4
Lakota warrior Black Moon has fought long and hard against the Long Knives, but in the aftermath of the Battle of the Little Bighorn, his people are forced onto agencies where they live at the mercy of the soldiers and bend to the will of the white man. The death of a beloved friend has plummeted him into a well of uncertainty over his ability to keep the people safe at a time when a new enemy, the Northern Pacific Railroad, threatens their future. To safeguard her family from this latest threat, Katie strikes a bargain with the government, but it is a bargain that comes with a high price. And as Black Moon struggles against the most important battle he will ever fight -- the one within himself -- peace and acceptance come from a most unexpected source.
