I like the characters and I think the story flows well. I don't think think the post apocalyptic scenario is believable in this setting. So humanity just kept fighting until only a few a hundred million people were left? We didn't stop at a quarter of the world population, or at half. It wouldn't take anywhere near that for all the governments to shut down and create chaos. Anyway I dwelt on the one point too long. There is a lot of wit in your writing. I'll definitely keep reading.
