Fire in the Heavens (1958)

OPERATION WORLD'S ENDJeff Benson and Lucille Roman stood worlds apart in their approach to science. Jeff, an instrument engineer, was interested only in its purest aspects. Lucille, a rocket manufacturer, thought only of its profit-making potential.It was a one-in-a-million chance that their worlds would ever collide. But when the sun threatened to go nova—to incinerate the Earth in one devastating explosion—these two found themselves in a highly combustible partnership.Only Jeff could possibly avert the coming catastrophe, and he could do it only with Lucille’s co-operation. Upon the success of their emotion-charged alliance hung more than the future of science. The very fate of Earth depended on their working—or dying—together!
