Illus. in black-and-white by Sal Mudocca. "With an entertaining blend of fact, farce, and fantasy, Osborne tells the story of Jack and his sister, Annie, who take a trip in a magic tree house and land in a time 65 million years ago. They find dinosaurs and volcanoes and adventure. Veteren storyteller Osborne builds the power of reading into the story: it"s the books in the tree house that give the kids the magic to travel and see far, far away."--Booklist
