THE WORLD IS ENDING—AND ONLY LOVE CAN TIP THE SCALES. Anna Walker’s final quest takes her to the Ark of the Covenant, the most powerful relic of all. But time is slipping away. The Brotherhood has torn Kincade from her side, and the Knights of the Holy Lance have unleashed an army engineered from her own bloodline. And when the Four Horsemen ride, the world itself begins to burn. With Lucifer’s victory nearly complete, Anna and Kincade must risk everything to seize the Ark. Together, they will face devastating betrayals, impossible choices, and the final battle that will decide the fate of mankind. But the war between Heaven and Hell will demand the ultimate sacrifice. To save humanity—and each other—they must prove that love is the one force even Lucifer cannot break. NARRATED BY THE AUTHOR. A breathtaking finale perfect for fans of Jim Butcher, Ilona Andrews, and apocalyptic urban fantasy filled with danger, sacrifice, and love as fierce as the end of days.
