Following the catastrophic final jump of the Pillar, Grant Mc Kay is stranded in the farthest reaches of space, adrift on the wreckage of his former self. Before he can reclaim his mantle as protector of the Eververse, he must first overcome the demons that lurk within his own soul. And when his path finally leads him back home, what has happened while he was gone? In a world of infinite possibilities, what can one man do to keep everything that could ever possibly go wrong from doing so? Collects BLACK SCIENCE #16-30
