Mark Twain 
A Connecticut Yankee in King Arthur’s Court [EPUB ebook] 

Written in 1889, Mark Twain’s
A Connecticut Yankee in King Arthur’s Court is one of literature’s first genre mash-ups and one of the first works to feature time travel. It is one of the best known Twain stories, and also one of his most unique. Twain uses the work to launch a social commentary on contemporary society, a thinly veiled critique of the contemporary times despite the Old World setting.
