Oz House finds itself threatened when foster children start to disappear—again. Years ago it was Suzy Bishop. Now it's little Buddy Samson and Jessica Holton. In the desperate search to find the children, no one could guess that Buddy is wandering the streets of Mother Goose Land in search of his family, who perished in a fire, or that Jessica, to find him, is opening dangerous doors in one magical world after another until all of fairyland is threatened, from the Forest of Grimm to the Emerald City of Oz. No one, but Charles Emerson. And he can't tell.
