Tree of Smoke

A CIA operative's descent into paranoia and obsession while compiling a massive index of intelligence cards (the "Tree of Smoke") during the Vietnam War, told through a fragmented, hallucinatory narrative structure — this is literary fiction at its core, not a thriller or war novel, despite the Vietnam setting. The tone is elegiac and hallucinatory rather than tense or gritty, and the themes are war's dehumanizing effect, the fragility of identity, and the moral ambiguity of intelligence work. No romance or coming-of-age tropes apply; the book is a meditation on memory and loss rather than plot-driven genre fiction.
