When Henry's parents are kidnapped by terrorists, Henry goes to live with his aunt, uncle, and three cousins, in Henry, Kansas. He is given the attic bedroom and is surprised one night by thumps on the wall. Plaster begins to fall away from the wall and Henry glimpses two knobs. As he pulls more plaster away, he realizes the knobs are attached to a door. His cousin Henrietta helps him pull more plaster away from the wall, until 99 small cupboards are revealed behind the wall, each with a different appearance. Soon Henry discovers that these cupboards lead to different worlds, but many are locked and too small for him to go through; however, they are not too small for things to come into his room through the cupboards! He and Henrietta embark on a quest to discover the mystery of the cupboards. Lovers of fantasy will enjoy these books. The author has a quirky sense of humor, and some random comments are difficult to understand. I was bothered by Henry's indifference to his parents' situation, but I still enjoyed this book.
Caution: There is some violence and an evil witch, much like Narnia's White Witch. The author is a Christian, and parents may recognize the author as the son of Douglas Wilson, who writes and publishes homeschool classical curriculum.
