Henryk Adam Aleksander Pius Sienkiewicz (Polish: [ˈxɛnrɨk ˈadam alɛˈksandɛr ˈpʲus ɕɛnˈkʲevʲit͡ʂ]; also known by the pseudonym "Litwos" [ˈlitfɔs]; 5 May 1846 – 15 November 1916) was a Polish journalist, Nobel Prize-winning novelist, and philanthropist. He is best remembered for his historical novels.

Excerpt
This is a two-volume work, the sequel to "With Fire and Sword," a massive book called one of the greatest in European literature. "The Deluge" continues the sweeping saga of war and rebellion that threatened the kingdom of Poland and changed the face of Eastern Europe in the 17th Century. This historical novel of Poland, Sweden and Russia, is a masterful blend of history and imagination, filled with nonstop action and adventure. Sienkiewicz's work is the sweeping saga of a nation caught in the throes of a civil war, of a people struggling for survival, and of events that forever changed the face of Eastern Europe. Number two in his trilogy on the history of Poland, it tells the love story of a man and a woman tragically separated by foolishness, pride, confusion and the Swedish invation of Poland in the 1500s which divided a nation against itself and drew the best and worst out of its citizens.

The cover or the title page is wrong:

Cover: In Modern Translation by W.S. KUNICZAK
Title page: AUTHORIZED AND UNABRIDGED TRANSLATION FROM THE POLISH BY JEREMIAH CURTIN

Since it includes an introduction by J. Curtin, I'm inclined to believe the cover is wrong.
