When Blake Walker foiled a murder attempt on one of his neighbors he somehow found himself drafted into a frantic chase for a dangerous criminal - through the almost infinite levels of alternate Earths.
It was a chase that would take him through level upon level of unknown dangers in search of a ruthless genius who had found our Earth the perfect place to begin his series of conquests.
