Shadows from Boot Hill by L. Ron Hubbard

Brazos, the color and texture of sunbaked brick, was not generally given to nerves.  In fact, Brazos could generally look at an opponent and find bravado enough to grin a bit between shots.  Brazos had been raised in a very dark school wherein a man dead was a man safe.  And now all he had to do was use his expert skill to the end of putting three shots into three men and he would collect two hundred dollars and be able to hie himself southward, over the border and beyond the reach of those who had objected so surprisingly to the demise of a mere banker.

But somehow, cat-footing down the street through the predawn dark toward the marked stable, Brazos did not in the least feel like grinning.  His fingers, time and again, sought for the little silver cross at his throat. (taken from the back of the book)

I had so much fun with this book!  It's a western, but with a dash of paranormal thrown in.  As a character, Brazos is bold and colorful.  However, he's in the middle of a rough time in the west.  Things are changing.  Bankers and peaceful men are taking over the town.  Not only is Brazos in a difficult position, he's in a world that's different from the one he's always felt safe in.  Well,as safe as any gunslinger could possibly feel.  At least he understood that world.  This new one is incomprehensible to him.

This book is full of action and shooting and a good measure of self-discovery tossed in.  Brazos is a bright man and you'll see some of the surprising antics he pulls off.  Brazos is a unique character in that he realizes it's his world and so it's up to him to protect it.
