This was excellent. It based its portrayal not just on the facts of the events, but the facts of the emotional lives of the souls involved on all sides, even those whose claim to having a soul was tenuous. It made sense of the chaos with the benefit of a decade of hindsight and sought to teach the reader about the complexity behind every case of mass shootings we lump together as an epidemic of the same repeated tragedy. They’re not. I’ll admit morbid curiosity got me to read this, but I came away understanding a lot more about human reaction to the inexplicable. My only critique is it got a little long and dragged out towards the end.
