A post-apocalyptic tale beginning in a new dark age sounds like a bleak read. Thankfully Walter M. Miller Jr. quickly makes it clear that humor is still a viable asset in a sci-fi novel that's heavy with meaning. A Canticle for Leibowitz is by no means a comedy, but when used moderately, Miller's humorous injections add an extra layer that separates this classic from sci-fi works with similar themes.
