"Ataman Chaika". The stunning plot of the book, whose main characters are real historical figures, will not leave the reader indifferent. Ivan Korsak, using archival materials, reconstructed and comprehended the history of Ukraine in the nineteenth century. The life of Ataman Chaika (1804-1886), a "Pole with Ukrainian blood type", is filled with the spirit of adventurism and amazing, sometimes paradoxical, twists of fate.

The Nemyrychiv Key is a novel by Ivan Korsak about the first and only Ukrainian Chancellor Yuriy Nemyrych. The author managed to show the extraordinary nature of this figure, to emphasise the idea that it is no less noble, and perhaps even more important, for intellectuals to win at the desk than with a sabre in their hands.
