The first Magic Tree House book was published in 1992 — introducing the world to Jack and Annie, a brother and sister who discover a magical tree house filled with books. In Dinosaurs Before Dark, the tree house takes them on their first journey, an adventure in prehistoric times. Since then, the magic tree house has whisked Jack and Annie — and lucky readers! — on many more adventures through time to different places around the world.
