London's burning. As demons hunt down those few inhabitants caught within the flaming borders of the city, the angels and their dark cousins gather across the river. Even the suburbs are quiet as the military attempt an enforced evacuation. Caught within the Hell of the city, the priests and police who survived the battle at the palace work on a way to evade the stalking demons and attempt to flee through the fires. Jade, the instigator of the mayhem has become a plaything of Lucifer and even Mastema feels his activities curtailed by the presence of the devil. To release Hell's grip on London there are tasks that must be accomplished. With the angels unable to cross into Hell, it falls to the dark angels and humanity to seek a resolution. The agreed plan hinges on Rachael and Anthony; the youth must accompany the dark angel into the deepest realm of Hell and into the throne room of Lucifer himself. Those left behind are not idle. If any stage of the plot fails, the world will be lost to the immortal offspring of the devil's bride.
