I happened on this while looking at “suggestions” after finishing Circle of Hope by Eliza Griswold  https://mybecky.blog/2024/08/23/circle-of-hope-by-eliza-griswold .  Junger is a journalist, author and filmmaker and that sounded interesting as did other of his books.  I looked into it further and was still interested,  but it was also available at the library so I waited – I was in no rush.

And it is a very interesting book and I may read more by Junger. He’s earned a reputation for writing about moderately common psychological issues. This book is about how human beings seem to be naturally drawn to small and close-knit groups or communities and later feel lonely and isolated.  It’s also about war, PTSD and anti-social behavior like mass shootings. Toward the end he gets very interested in recovery from PTSD.
