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.

School Library Journal

Gr 1-3-- This enjoyable time-travel fantasy is a successful beginning chapter book. Jack and his younger sister find a tree house filled with books. When he wishes he could really see the Pteranodon pictured in one of them, it appears at the window. The children have been transported back to the Cretaceous period. They begin to explore and are soon threatened by a Tyrannosaurus. The Pteranodon comes to their rescue, and they figure out enough about the magic that carried them back in time to be able to use it to return home. There is plenty of suspense and magic here, and enough dinosaur information to please science buffs. Characterization is sketchy and older children will find the plot predictable, but readers just past the easy-to-read stage will find it satisfying. It should attract those who devour Ruth Chew's books. --Louise L. Sherman, Anna C. Scott School, Leonia, NJ
