Through the ancient magic of the Grigori, the rogue Anakim, Peverel Othman, is once again Shemyaza, king of the fallen angels, benefactor of humankind, who was once doomed to an eternity of torment and imprisonment. Now his soul is free and incarnate in the world, and as the millennium draws to a close, Shemyaza calls his followers to him for the final battle to decide who controls the fate of humanity. Along with his brother Salamiel and his human vizier Daniel, Shemyaza journeys to seek the place of his creation; Kharsag, the Garden in Eden. Along the way they fall in with the Yarasadi freedom fighters, who are inspired by a dynamic new leader whose identity is an enigma. In the mountains of these eastern lands, Daniel discovers a forgotten part of himself and begins to learn the secrets buried long ago by the forebears of the Anannage, the original angel race. In Babylon, a new human king has arisen, who believes he is the descendent of the angels and in an ancient buried city discovers a Watcher Lord who has been imprisoned for millennia. With the aid of this being, the king sends out the djinn to track down Shemyaza, who is essential to the schemes of the Babylon mages. Meanwhile, the assassin Melandra Maynard, driven by the creed of the cult in which she was raised, has been given the task of hunting down the king of the fallen ones and killing him. All these forces converge and combine in the mystical land of Egypt, where Shemyaza must make the ultimate sacrifice, bringing the Grigori trilogy to a breath-taking conclusion.
