Set partly in the present and partly in the future, Eros Triumphant centers on Andora Panvion, a wealthy predator of plutocrats preventing humanity from organizing an orderly exodus from our solar system. The bloated Sun evaporated Earth's oceans. A global desert stretches between the tropics of Capricorn and Cancer while the poles bear the only seas and vegetation. Humans live in subterranean cities across the solar system and several alien star systems. Around the galaxy's central black hole, a ring 3.14 light-years in diameter bears oceans, landmasses, cities, and form-shifting beings fond of existentialism. Eros finally kills Thanatos.
