The time is the Beginning. The place is Heaven. The story is the Revolt of the Angels--a war of magic, corruption and intrigue that could destroy the universe. Tor Essentials presents new editions of science fiction and fantasy titles of proven merit and lasting value, each volume introduced by an appropriate literary figure. Originally published in 1984, Steven Brust's To Reign in Hell is a retelling of Satan's revolt against Heaven with much more sympathy for Lucifer and his allies. Heaven is threatened by the reemergence of a cataclysmic event, a wave of energy that can destroy life and result in the loss of many angels. In preparation for this Fourth Wave, the angel Yaweh consults the angel Satan. A plan to build Earth, a new and larger Heaven that would be equipped to withstand the disaster is constructed. Satan questions the plan because doing so will sacrifice the lives of other angels, much like the Fourth Wave itself threatens to do. Charged with convincing their fellow angels to lay down their lives, Satan has reservations about their right to ask for such a sacrifice. This doubt, and the questioning of ethics, opens the door for a devious figure to manipulate Satan, developing a heavenly war. This re-examination of Paradise Lost calls morality and villainy into question through the lens of epic fantasy is a prescient early classic with an enduring legacy and a formative text of the genre. With an introduction by the late, great Roger Zelazny, author of Lord of Light and Nine Princes in Amber.
