LONDON, 2038 The once-great city lies in ruins. A massive gash in the fabric of our reality roils against the horizon as it blends into a permanently darkened sky. The world as we know it has come to an end. Demons, the visions of our nightmares, walk the Earth. Mankind, driven in retreat to the sanctuary of the Underground, struggles to survive the Hellish apocalypse. Among the survivors are those who foresaw the coming of the darkness, those who see it as an opportunity to improve the standing of man, and those who seek revenge for what was lost. All are now banding together in the shadows, arming themselves with futuristic weapons and arcane spells designed for one purpose—to battle the demonic hordes and take back their world.

The trilogy that began in Exodus continues: 2024: Four years after the Demons opened the planar rift known as the Hellgate, mankind's desperate struggle to survive continues. Simon Cross, expatriate of the secret Templar order, works to find and transport survivors out of the ruined city. Hiding within London's Underground system, Simon is raising an army to fight against the encroaching Darkness. Now, he battles the monsters that roam the city and fends off a jealous Knight who plans to take Simon down...all while striving to reunite the divided Templar forces. Warren Schimmer, a Cabalist who is magically linked to a powerful demon, searches for Goetia. Also known as the Lesser Key of Solomon, this ancient artifact could provide the forces of good or evil with an edge in the ongoing war. Standing in his path is Simon Cross. Warren has made a bargain with his Demon lord for survival and the promise of vengeance against the persuasive Templar...but a Demon's promise is made to be broken.

As Templar Simon Cross fights to lead the hunted survivors of the demon surge toward salvation, time and supplies run short. Simon must penetrate the dark secrets of the demons—as well as those of his partner in peril, Leah Creasey—to keep his charges safe. But Leah's organization won't surrender their knowledge easily, even as new technology emerges from the Goetia Manuscript that could help Simon's cause. Warren Schimmer, linked to one of the darkest of the hellspawn—the demonic Lilith—is himself also targeted by infernal forces. No longer able to hide, Warren must emerge as a leader and turn a ragged band of Cabalists into an army. But when a vicious weapon that uses dreams against the human survivors of the city draws the Templars, the Cabalists, and the Hunters into the same arena, will they join forces...or turn against one another?

MI5 agent Lyra Darius discovers a human charnel house in the heart of London while tailing Lord Sumerisle, the recently resigned Home Office Minister for Internal Affairs. She's soon entangled in a bloody intrigue with Knights Templar, and everything is building up to All Hallows Eve.

In the year 2020, a demon invasion strikes several cities around the globe, including London, home to college Rugby champ John Fowler and his family, but before the climatic Battle of All Hallow's Eve, John and his sister Lindsey attempted to discover the story behind what seemed to be a series of bizarre an exhumed skeleton, a haunting apparition, and a powerful sword that they find in their attic.
