The Sleeper Awakes is a dystopian science fiction novel by English writer H. G. Wells, about a man who sleeps for two hundred and three years, waking up in a completely transformed London in which he has become the richest man in the world. The main character awakes to see his dreams realised, and the future revealed to him in all its horrors and malformities. The text published as The Sleeper Awakes in 1910 is a revised version of the novel When the Sleeper Wakes, which was published as a serial, then as a book, in 1899. The 2004 Project Gutenberg title page displays on four lines that suggest a subtitle: The Sleeper Awakes; A Revised Edition of “When the Sleeper Wakes”; By H. G. Wells; 1899. Library of Congress Catalog uses the subtitle. Source: Wikipedia (en)
