A Canticle for Leibowitz - Walter M. Miller Jr. Considered a classic for post-apocalyptic fiction, "A Canticle for Leibowitz" is a study in the timelessness of human nature and the folly of expecting that nature to change.

"A Canticle for Leibowitz" is a set of three vignettes, told at different periods after the Earth is destroyed in a post-WWII era apocalypse. Issac Leibowitz, an electrical engineer of the then-modern era, survives a nuclear holocaust and then makes it his duty to preserve as much scientific and cultural history as he can. This task eventually becomes the sacred duty of an order of monks. Over a period of centuries, the books and texts are preserved and eventually made available to the scholars of a new scientific renaissance.

I enjoyed the first two stories very much but found myself skimming the last one, mostly because I knew what was coming and I was no longer engaged in the story. I am glad to have read this, as I do love the genre.
