In book three, Will and his companions need to use deception and thievery to escape his evil grandfather's clutches, rescue Will's mentor, and save the planet from otherworldly creatures bent on destruction. Science and technology blend with mystery, mysticism, and some teenage attitude as the protagonists fight for their lives. The pacing suffers midway, but action gets things back on track.
