Thomas will turn thirteen in one week. He is looking for a leaf for a school project when the school bully, Butch, chases after him on his bicycle. Told never to be close to the river alone, Thomas now rides along the dangerous trial hoping to elude Butch. Suddenly, the ground beneath him gives away. He and Butch find themselves falling into a void; a tunnel that takes them to a primitive land. Taylor wonders what dangers lay ahead? Will they find their way back home? Was this all preordained...and if so...why?
