Mary Wollstonecraft Shelley 
Last Man [EPUB ebook] 

Mary Shelley states in the introduction that in 1818 she discovered, in the Sibyl’s cave near Naples, a collection of prophetic writings painted on leaves by the Cumaean Sibyl. She has edited these writings into the current narrative, the first-person narrative of a man living at the end of the 21st century. (Excerpt from Wikipedia)
