In a world run by an authoritarian government and enforced by the Special Police, scientists are kept virtual prisoners, made to run the atomic plants that power the great cities. Secretly, a small number of scientists have been plotting a revolution. Scientist Brad Lilling is caught up in plots and counter-plots. Hunted by the authorities as well as by the scientists who conspire against them, Brad may be the one person who can save Earth’s cities from entombment—and death! This classic pulp science fiction novel originally appeared in Thrilling Wonder Stories in 1948.
