Once is a 2005 children's novel by Morris Gleitzman. It is about a Jewish boy named Felix, who lived in Poland. Although Once is a work of fiction, Gleitzman was inspired by the story of Janusz Korczak, the events of World War II, and Hitler's attempt to exterminate the Jewish population of Europe. The sequel to the book is called Then.
