John Constantine, Hellblazer Vol. 6: Bloodlines

It's not often that John Constantine, the world's greatest magician, has been able to be content. Years in the making, his occult knowledge and shrewd judgment are hard-won and paid for in blood-his own, his friends', and that of innocent caught up in the never-ending arms race of would-be sorcerers chasing power. But after saving the world a few times and beating both the Devil and lung cancer, Constantine is finally starting to feel ahead of the game. However, between investigations of a grisly serial murderer and strategies against the Lord of Hell, John has no time to rest. Collects issues 47-50, 52-55 and 59-61 of the signature Vertigo series by PREACHER creator Garth Ennis.
