Gr. 1-2. 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. She leads most of the time; he worries a lot and takes notes, but he saves her when she's chased by a duckbilled anatosaurus. Later, Annie saves Jack with the help of a flying pteranodon. And they get home before dark. This First Stepping Stone Book is the first in a projected Magic Tree House series about time travel. Shared imaginative play is a great way to lure new readers to the pleasure of books. In fact, 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.
