Simone and Vance are settling into his life with disturbing ease, and David is beginning to look upon the two street orphans with a fatherly affection, especially with regard to the tiny and vulnerable Simone. But then something drastic happens.

However, when the brazen thief is finally discovered, his motive for the theft comes as a major surprise to everyone. A further development occurs when David and his companions decide to team up with the robber in order to help in his quest. In doing so, they end up on an amazing world filled with wonders, along with a plethora of deadly creatures.
