Harvard professor Feitlowitz interviewed Argentines from all sectors of society for this intensive study of the "Dirty War," which claimed 30,000 victims from 1976-1983. The cumulative impact of the testimony the people who were arrested, imprisoned or "gone missing" by the military is profound. A wordsmith by trade, the author looks at how activists, bystanders, victims and family members modified language to discuss the unimaginable horrors of this time.  (ARG27, $19.95)
