A good friend pointed me to this Pulitzer Prize-winning work (and it did not disappoint). The author does an exceptional job of weaving together the complexity of the science, the scores of actors, the horrors of war, and the questions of ethics.
My only complaint would be, at risk of sounding too much like a homer, that I wish Rhodes would have spent a bit more time delving into Hanford. Just last summer I had the opportunity to go to the B Reactor Tour. Incredible breakthroughs right in my backyard. Likewise, one of the items on my bucket list is to visit Hiroshima or Nagasaki (in an attempt to see both sides of history while learning from the harsh lessons of humanity).
