Letters from Abu Ghraib, a collection of email messages sent by Joshua Casteel to his friends and family during his service as a US Army interrogator and Arabic linguist in the 202nd Military Intelligence Battalion, is the raw and intimate record of a solider in moral conflict with his duties. Once a cadet at the US Military Academy at West Point and raised in an Evangelical Christian home, Casteel finds himself stationed at Abu Ghraib prison in the wake of the prisoner abuse scandal. He is troubled by what he is asked to do there, although it is, as he writes, "miles within the bounds of what CNN and the BBC care about." Forced to confront the nature of fundamentalism, both religious and political, Casteel asks himself a fundamental question: "How should I then live?"
