The n-Body Problem

In the end, the zombie apocalypse was nothing more than a waste disposal problem. Burn them in giant ovens? Bad optics. Bury them in landfill sites? The first attempt created acres of twitching, roiling mud. The acceptable answer is to jettison the millions of immortal automatons into orbit. Soon Earth's near space is a mesh of bodies interfering with the sunlight and having an effect on our minds that we never saw coming. Aggressive hypochondria, rampant depressive disorders, irresistible suicidal thought--resulting in teenage suicide cults, who want nothing more than to orbit the earth as living dead. Life on earth has slowly become not worth living. And death is no longer an escape.
