When three children move to an old house in rural Georgia, they have no idea the secrets the house holds for them. Soon the Christopher children find magical fun in the basement, and portals that transport them to places of both beauty and of terror. Who can they trust? How will they travel to these other worlds, and how will they get back? Their lives are complicated more when they discover other children, trapped in a house of fear and slavery, and only the Christopher children can rescue them. Will they succeed without becoming prisoners themselves?
