After the disaster, Father and Son go through the scorched lands, crossing the continent. The whole book is riddled with deep, heart-wrenching questions. Does it make sense to live if there is no future? Not at all. Does it make sense to live for children? This is a novel about how everything in life is relative, that such concepts as good and evil, in certain conditions, stop working and lose their meaning. This is a novel about what is really important in life, and how to appreciate it. And it's also a novel about death, about how everything ends some day, and so you need to take every day as it is. You just need to... live.
