Warren Ellis' masked hero masterpiece goes nuclear in this cataclysmic final issue! John Horus has brought the weight of the world down on himself, yet he is far from defeated. As the body counts rockets skyward, desperate attempts are made to bring down the President's killer. Not even the combined might of the last few living members of the Seven Guns seems to be enough. You do not want to miss this shock ending that will cement this work as a high-water point for the genre.
