Twelve-year-old inventor Jack Boomershine believes it a practical joke when a mysterious text message directs him to it. But finding this powerful stone sets in motion an entangled clockwork of events that draws him ever deeper into an adventure in which his inventions are useless.
As things spin out of control, Jack must find his way through a hidden world of magic with vehicles that fly themselves, a telepathic creature-and an ancient evil with an unfathomable plan, determined to ensnare Jack in it.
