Jostein Gaarder writes philosophical fiction that introduces major ideas through stories, puzzles and young protagonists. Sophie's World follows fourteen-year-old Sophie Amundsen after she begins receiving mysterious lessons on the history of philosophy, moving from the pre-Socratics through thinkers such as Plato, Descartes and Kant while a second narrative gradually questions the reality of Sophie's own world. The Solitaire Mystery uses a family journey and a strange deck of cards for another story about identity and wonder, while The Orange Girl combines a father's message with questions about love and existence. Gaarder's prose is accessible and idea-led, fitting philosophical fiction, YA crossover and educational novels about the history of thought. Read more Less
