Lila Prap (1955), writer and illustrator, Hans Christian Andersen Award and Astrid Lindgren Award nominee, has developed a recognisable, humorous style featuring her signature pastel on paper drawings. She gained international recognition and popularity with her series of children’s books 1001 pravljica (1001 Stories) (Mladinska knjiga, 2005), Moj očka (Daddies) (Mladinska knjiga, 2009), Dinozavri (Dinosaurs) (Mladinska knjiga, 2009), Pasji zakaji (Doggy Whys), (Mladinska knjiga, 2010) Mačji zakaji (Cat Whys), (Mladinska knjiga, 2013) and Zakaj? (Why?) (Mladinska knjiga, 2002; latest edition 2022). Her works have been translated into several world languages. The Japan National Television (NHK) based an entire cartoon series and accompanying merchandise on the characters from her books. Her picture storybooks from the Why? series encourage readers to seek answers to various questions with numerous nonsensical conclusions that always end up with the right, scientifically- proven answer.
