InterWorld

Joey Harker isn't a hero. Joey Harker is the kind of guy who gets lost in his own house. But one day, Joey gets really lost. He walks straight out of his world and into another dimension. This walk between worlds makes Joey prey to armies of magic and science, both determined to harness Joey's power to travel between dimensions. The only thing standing in their way is Joey - or to be more precise an army of Joeys, all from different dimensions. Now Joey must make a choice: return to the life he knows or join the battle.
