His latest discovery? The lions in front of the New York Public Library are actually sphinxes, guarding a secret treasure trove of magical objects. When a mysterious wizard steals a powerful wand from the collection and casts a spell on the entire supernormal world, Stephen and his friends must find a way to reverse the magic before it becomes permanent"--Provided by publisher.
