Sixteen-year-old John has stumbled across an abandoned wristwatch half-buried in the sand behind his house. Curious, he places it on his wrist; to his surprise, it won’t come off. Suddenly, each day at 3:14 P.M. John begins to uncontrollably teleport around the world. He might materialize anywhere--a burning African desert, a Canadian forest, even a Siberian prison--and must do what he can to survive until 3:14 A.M. When the watch takes him home again. But John's adventures come with a price... When a scientist mysteriously trapped far below the surface of the Earth makes contact through a hologram on the watch's face, John learns that his travels will eventually kill him. Soon, he's faced with an impossible choice: continue to endanger his life by using the watch, or switch places with the scientist and risk losing his freedom forever.
