In the depths of the Utah desert, long after the earth has been scoured clean, a monk of the Order of Saint Leibowitz has made a miraculous discovery: holy relics from the life of the great saint himself, including the blessed blueprint, the sacred shopping list, and the hallowed shrine of the Fallout Shelter. In a terrifying age of darkness and decay, these artefacts could be the keys to mankind's salvation. One of the most accomplished and enduring classics of modern speculative fiction, Walter M. Miller's A Canticle for Leibowitz is a true landmark of 20th-century literature - a chilling and still-provocative look at a post-apocalyptic future.
