The Lord of Death and the Queen of Life

Two worlds with very different futures for humanity... In The Lord of Death, four scientists, aided by reverse-magnetism, travel to a dead planet where they discover that one human's lust for power destroyed all life there-except for him. In suspended animation, he awaits the newcomers. In The Queen of Life, the scientists travel to a planet encased in a glass sphere to protect the overpopulated planet from the sun's radiation.
Conflict leads to a riot.
