John Constantine is returning to a grittier part of the DC Comics' stable with October's one-shot The Sandman Universe Presents Hellblazer #1.
This is followed in November by a new on-going series from Simon Spurrier and artist Aaron Campbell: John Constantine, Hellblazer.
The DC Comics blog tells us that:
"In The Sandman Universe Presents Hellblazer #1, the story begins in a moment originally seen in [Neil] Gaiman’s miniseries The Books Of Magic. John Constantine finds himself haggard, bloody, and dying in an epic magical war—a battle that will soon consume the world. As he lies there, the vision of a young Tim Hunter stands above him, the naive youth seeing firsthand what his destiny holds. Horrified, Hunter flees back into the past, and Constantine is left behind to die.
Now, years later, Constantine reemerges, physically un-aged but with all of his memories intact—and yet the world has passed him by. Constantine must now fathom a new world torn apart by the same old political and social woes, while attempting to discover how he returned after all this time. But most troubling of all are the rumours of a new young magician named Tim Hunter, a boy destined to be either the greatest sorcerer of all, or the greatest threat to the world. If history is repeating itself, then is it John’s role to die all over again? Or is John here to stop the cycle—and stop Tim Hunter?"
