Review

"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. Veteran 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."
