Het Punt Omega by Don DeLillo

An austere, tightly controlled narrative follows an aging former government adviser who has retreated to an isolated glass house in the desert and the younger filmmaker who comes to record him; their terse conversations and long silences become a probe into memory, loss, the moral aftershocks of modern war, and the way consciousness stretches and collapses around events. Spare, elliptical scenes and a cool, observant tone turn a simple visit into a philosophical standoff about time, perception, authorship and the limits of explanation, leaving much implied rather than spelled out.
