She claims her name is Varloo and that she is a spy from an underground world called Hek.... She says she has been sent to report what the people on the surface are up to, especially anything that might threaten her world below...But Varloo doesn't seem like any spy Dougie Minners ever heard of. She is short, klutzy, and she wears a long dress that looks like a bathrobe Still, Dougie is not about to leave Varloo lying bruised beside a creek in the woods. So he takes her to the only safe place he knows -- his tree house.Life aboveground is not as bad as Varloo expected, especially when it comes to food. Mushroom cakes and turnip wafers aren't nearly as delicious as Oreos, Kool-Aid, and the red sauce called catsup Then suddenly she and Dougie hear of a plan that might mean the destruction of Hek. Now it's up to these two unlikely heroes to save an entire underground civilization. How on Earth...or in Hek...will they do it?
