Good well told Western tales in the usual L'Amour style. Hard-bitten Western men, hard working, hard riding quick on the draw, straight shooters in all sense of the term. Lonely, attractive woman needing saving. Yada Yada Yads. Like I said, typical.
Louis L'Amour has written better, much better, but these were still good-reads just more-of-the-same. Even the pasture in the lava field wasn't new. He used it at least once before, Talon I think.
The first story was interesting mainly for the Walch 12-shot Navy and mention of the. 44 Russian. His attention to authentic Western history has always been one of his strengths that set him apart from other Western writers.
I've owned most of L'Amour's books, and read a lot of the rest. The least of them were reading once. Many were reading many times.
