He Who Comes [EPUB ebook] 

When they crossed Reuben Cole, they signed their death warrant.
Reuben Cole is not the sort of man they should have messed with, and breaking into his home proves a bad idea. After his friend, Sheriff Roose, hunts down the robbers who took everything of value, the reasons for the burglary are revealed and a crooked railroad magnate’s ambitions exposed.
Cole’s enemies are about to learn that the ways of the Old West, despite it being a new century, are not quite over yet.
