That's the question Jack and Annie have about gorillas when the Magic Tree House sweeps them to the mountains of Africa. There they meet a group of amazing and sometimes frightening mountain gorillas. Annie knows how to play with the creatures right away. But Jack is left out. Will the gorillas be able to teach him some special magic?

You'll go ape over...

One summer day in Frog Creek, Penn-sylvania, a mysterious tree house appeared in the woods.

Eight-year-old Jack and his seven-year-old sister, Annie, climbed into the tree house. They found that it was filled with books.

Jack and Annie soon discovered that the tree house was magic. It could take them to the places in the books. All they had to do was point to a picture and wish to go there. While they are gone, no time at all passes in Frog Creek.
