In a post-nuclear desert monastery, long after the fall of civilisation, monks work to illuminate scraps of blueprints and memos they regard as sacred relics. Their mission? To preserve what little remains of human knowledge – even if they don’t fully understand it. Spanning millennia, Miller’s Hugo Award-winning and genre-defining novel is both epic and eerily intimate, charting humanity’s habit of repeating history with all its miracles and mistakes. Philosophical, quietly funny and disturbingly prescient, A Canticle for Leibowitz is science fiction at its most thoughtful – and its most human.
