Long ago, back when the New York Times was a well-regarded paper, I saw a quote from a NYTimes review of a Western (as stated, they were once a decent paper)that said "emotionally mature". That description fits this book.
This book is a complex morality book;,twists and turns abound as courage turns to cowardice, cowardice to courage, ignorance to knowledge, loss to gain to loss. Jim Reno, the war-weary drifter, is a seeker for his place in life, but nothing comes easy for him. In the tough trail town of Rimrock, he faces not only himself but the lightning draw of a faster man.
Really a fine book that goes well beyond the average western in emotional depth.
