Picking up where This Paper World left off, Jim Hunt is at home with friends and family for summer break... but only briefly. He has committed to attend intense training to hone his new abilities at a Champion training camp in northern Maine. Upon arriving at the camp, Jim is introduced to his new teacher, Clyde, a crusty curmudgeon of a man who is determined to keep Jim on his toes. Sharing the camp is a talented young teen, Gabby, who hasn't "flipped her switch" yet, but has the potential to become a powerful Champion. While at the camp, a powerful enemy who has crossed Jim's path before strikes a devastating blow. Jim sets off on a solo journey of vengeance to bring retribution down on this evil being. Will Jim find the justice he seeks or will he lose his life and his soul in the pursuit?
