Back in the day, England was a place of ill-fated chivalric adventures, but what would happen if a modern American entered this world? In the book "A Connecticut Yankee in King Arthur's Court" by Mark Twain, the main character is the loser Henkle Goodwin, who finds himself in the Middle Ages, in King Arthur's court. It seems that he appeared in a fairy tale, but it turns out that being a hero in the cruel and dangerous Middle Ages is not as easy as it looks. Henkle decides to use his knowledge and entertainment to improve this world, but there are many obstacles, enemies and unexpected circumstances in his plans. This book is a fun and profound reflection on the nature of time, civilizational development, human wisdom and what it really means to be a hero.
