Anything Craig Johnson writes is worth reading, and this one is even better than some. It's a demand, not a plea, for open mindedness and acceptance of other people. The White Buffalo clan is an interesting new addition to Walt Longmire's world, and the book provides everything a mystery lover or just a good literature lover needs: questions and mysteries, strong personalities, deeper meaning, insight to life, realistic setting, danger, action, character development, and a further look into the character and culture of Native Americans. Longmire thrives on righting injustice and is often able to actually succeed in his endeavers.

Maybe I'm just getting old, but with the back and forth between 'present day' Wyoming and 1968 Viet Nam, I got confused from time to time. Still a good story.
I love the characters in this series, but this plot line was not as good as the three that preceeded it. But I'm hooked - even watching the TV series - and will remain faithful by reading the next one as soon as it's available!
