I would like you to take a look at C. G. Faulkner’s Western Trilogy.
Unreconstructed: A Story of the Old West, Vol. 1; Undaunted, vol.2; and Unrepentant, Vol. 3. Here is his Author Page (first page) from Author Central, Amazon.com: (A good buy.)

And here is his Facebook page from Facebook.com:

And I hope you enjoy Mister Faulkner’s work!
