Others have been visited and given powers like Minoru's, but their twisted desires are not so benign. When a murderous force threatens the people Minoru holds dear, will his newfound abilities be enough to stand in its way? And can there be a future for someone who craves eternal solitude above all else? The story of the Isolator begins here!
