Children of Men [EPUB ebook] 

The Children of Men begins in England in 2021, in a world where all human males have become sterile and no child will be born again. The final generation has turned twenty-five, and civilization is giving way to strange faiths and cruelties, mass suicides and despair. Theodore Faron, Oxford historian and cousin to the omnipotent Warden of England, a dictator of great subtlety, has resigned himself to apathy. Then he meets Julian, a bright, attractive woman, who wants Theo to join her circle of unlikely revolutionaries, a move that may shatter his shell of passivity. And maybe, just maybe, hold the key to survival for the human race.From the Trade Paperback edition.
