Continuing the hardcover collection of master comics writer Alan Moore's award-winning run on The Saga of The Swamp Thing, this fourth volume brings Swamp Thing's quest for self-discovery with the mystic John Constantine to its shattering conclusion.
A harbinger of doom has been released with the sole charge of waking an evil beyond comprehension, and Swamp Thing, John Constantine, Deadman, The Phantom Stranger, Etrigan the Demon, The Spectre and other masters of the occult must unite against the dark forces that threaten to eradicate Heaven's light.

Alan Moore is perhaps the most acclaimed writer in the graphic story medium, having garnered countless awards for works such as Watchmen, V for Vendetta, Swamp Thing and Miracleman. He is also the mastermind behind the America's Best Comics line, through which he has created (along with many talented illustrators) The League of Extraordinary Gentlemen, Promethea, Tom Strong, Tomorrow Stories and Top Ten. As one of the medium's most important innovators since the early 1980s, Moore has influenced an entire generation of comics creators, and his work continues to inspire an ever-growing audience.
