Paul Brians' "" (1987) is a study that examines atomic war in short stories, novels, and films between 1895 and 1984. Since this measure of destruction was no longer imaginary, some of these new works, such as Nevil Shute's "On the Beach" (1957), which was subsequently twice adapted for film (in 1959 and 2000), Mordecai Roshwald's "Level 7" (1959), Pat Frank's "Alas, Babylon" (1959), and Robert McCammon's "Swan Song" (1987), shun the imaginary science and technology that are the identifying traits of general science fiction. Others include more fantastic elements, such as mutants, alien invaders, or exotic future weapons such as James Axler's "Deathlands" (1986).
