In fact, he's the kind of guy who gets lost in his own house. But then one day, Joey gets really lost. He walks straight out of his world and into another dimension.

Joey's walk between the worlds makes him prey to two terrible forces—armies of magic and science who will do anything to harness his power to travel between dimensions. When he sees the evil those forces are capable of, Joey makes the only possible choice: to join an army of his own, an army of versions of himself from different dimensions who all share his amazing power and who are all determined to fight to save the worlds.
