While Denis Johnson's 'Tree of Smoke' may be regarded as the single best American novel about the Vietnam war, Tim O'Brien, who has turned writing about the Vietnam stories into a sort of cottage industry, has produced three outstanding books. Taken as a whole, these books achieve something far more captivating and significant. The first one, 'The Things They Carried,' offers an extremely personal perspective on the dehumanization and commodification of the war. It is told with a faux-bureaucratic detachment in the form of a series of inventory lists. The second, 'Going after Cacciato,' is a surreal black farce, comparable to the 'Catch-22' of its generation. 'In the Lake of the Woods,' on the other hand, is set decades after the war and deals with its irreversible aftereffects. In a worst-case scenario of PTSD, a seemingly successful veteran suddenly and spectacularly breaks down in a tragedy of epic proportions. This ostensible war hero, an up-and-coming politician, was involved in some particularly horrendous wartime carnage. Twenty years of denial has only managed to boil his guilt into a corrosive, explosive concentrate. Unlike Johnson, O'Brien is a Vietnam veteran, and this fact is evident - not in the portrayal of the details of the wartime experience, which Johnson captures just as accurately, or even in the moral ambiguities of war, but rather in the very specific ways that war annihilates the moral compass and drives men to madness.
