I’m a Polish writer. I write novels based on history. Especially I’m interested in Jagiellonian and Sforza’s dynasties, therefore I’ve written six books about them. ”A Princess of Milan” shows the story of Isabella of Aragona – Gian Galeazza Sforza’s wife. The next volume „Madonnas from Bari” presents Isabella’s life and gives us an image of her daughter Bona’s in Bari. The third volume describes Bona’s life and her rulling in Poland. In 1518 Bona married the Polish king Zygmunt and came to Poland to Cracow. She gave birth to four daughters and a son Zygmunt August. Although Zygmunt August was married three times , he never had children and the Jagiellonian dynasty died.
