The Scarlet Plague [EPUB ebook] 

Twelve billionaires rule the United States, while those called freemen are forced to serve the rich. But that was 60 years ago, before the Scarlet Plague. In this post-apocalyptic novella, a ragged and tattered old man tells his progeny of what life was like before The Scarlet Plague appeared — and wiped out civilization as they knew it.
