For all the hype I heard on this series I was a bit disappointed. The book is a second grade reading level (give or take depending on the child) with a kindergarten story line. It focuses on 3 children who are suppose to be cleaning out a basement and learn that the closet under the stairs is a gateway to another world, called Droon. They enter Droon, save a princess and go home. End of story. The overall concept for this series seemed to have potential but I feel the author could have done a better job and added more to it for the older children or shortened it and kept it a young children's book. Just my opinion, mind you.
