Level 7 (Library of American Fiction)

Level 7 is the diary of Officer X-127, who is assigned to stand guard at the "Push Buttons," a machine devised to activate the atomic destruction of the enemy, in the country's deepest bomb shelter. Four thousand feet underground, Level 7 has been built to withstand the most devastating attack and to be self-sufficient for five hundred years. Selected according to a psychological profile that assures their willingness to destroy all life on Earth, those who are sent down may never return.
    Originally published in 1959, and with over 400,000 copies sold, this powerful dystopian novel remains a horrific vision of where the nuclear arms race may lead, and is an affirmation of human life and love. Level 7 merits comparison to Huxley's A Brave New World and Orwell's 1984 and should be considered a must-read by all science fiction fans.
