Comeback is a five-issue mini-series written by Ed Brisson, illustrated by Michael Walsh and published by Image Comics/ShadowLine.
In the world of Comeback death isn't necessarily inescapable. The secret organization Reconnect sends agents back in time to rescue people moments before their untimely deaths, reversing tragedy and reuniting lost loved ones with their families. Mark is one of these agents, and despite the seeming good of what he's doing, he discovers there is a dark side to saving the dead.
Time travel... at a price.
