The story begins with DHI (Disney Host Interactive, or Daylight Hologram Imaging) day at the Magic Kingdom. Finn and the other DHIs are riding on a float when Philby (a DHI) notices a gray balloon on the castle. Due to the growing thunderstorm, however, it disappears in the crowd. The kids also notice that Chernabog, a character supposed to be on one of the floats, has gone missing. As the parade continues, Finn sees his old friend Amanda, and her sister Jez (Jess). We learn in this book that the characters have begun to be called Kingdom Keepers because of an adopted name given from a local newspaper. Amanda is trying to warn Finn about something when Charlene notices a pair of monkey-like creatures in the crowd. Jez slows, and Amanda (still trying to warn Finn) puts a leaf to her cheek. Realizing what she means, Finn knows that Maleficent is in the castle.
