"Like prison wardens and World Cup goalkeepers, book critics toss and turn over the ones that got away. The books they should have pounced upon, that is, but did not. One such book, people have been telling me, is "Full Body Burden: Growing Up in the Nuclear Shadow of Rocky Flats," by Kristen Iversen. Ms. Iversen's book was issued back in June. I'm getting to it now because I couldn't shoulder the guilt my hard-to-please wife is among its importuning admirers for another day. Ms. Iversen grew up in the 1960s and '70s in the small town of Arvada, Colo., about 10 miles from Denver, where most of the fathers worked at one of two nearby factories. The first belonged to Coors, whose weak brew was derided as "Colorado Kool-Aid." More mysterious, and thus prestigious, employment was found at Rocky Flats, a secret nuclear plant where employees made the plutonium warhead triggers for America's cold war nuclear arsenal."
