A Connecticut Yankee in King Arthur's Court

I read "A Connecticut Yankee in King Arthur's Court", so I explain this content a little.
Hank Morgan is a happy young man in Connecticut, USA in 1879 until one day. Someone runs into his office and shouts, 'Come quickly, Boss! Two men are fighting.' After this, something very strange happens to him, and his life changes forever. He experienced strange day.
Finally, he got back original century.
I think this story is kind of history and strange. It is difficult to understand and read this story, but please read it once!
