Westward — Harry Simpson

In the fourth novel of this epic Western adventure series, the son of a legendary frontier warrior comes into his own.
 
When Jake Elder left Missouri with his cousins to make a new life in the untamed Kansas Territory, he had no idea of the epic saga he was riding into or of the grizzly part he would play in it. To protect his home, he would have to become a killer.
 
In time, Jake's legendary exploits would earn him the name Badger Claw. And after he fell in love with an Arapaho woman, there soon came a new generation to carry the legend forward. This is the story of Billy Elder, a man who lives by his father's fearsome example.
