The world has changed. Septimus Bridge, greatest of all Demon Hunters, is gone forever. Only two of his former disciples remain to confront hellion invaders from the Netherworld. A far greater threat, however, looms, and the portents are impossible to ignore. Izanami, who has not dreamed in decades, is plagued by nightmares. Her partner Sapphire has gone missing. As hysteria takes over the airwaves and social media, law and order breaks down around the world. In the most worrying sign, the dead have returned to walk the earth. What is the secret of the mysterious crystal that has fallen into Izanami's possession? Who are the Zen'ei, and what explains their relentless control of so many minds all around the world? Why are ruthless Mercenaries hunting a young boy, who has no memory of who is or where he came from? Can Izanami, alone and on the run, keep him alive long enough to solve the mystery? As the truth is revealed, all hope appears lost. The Old Ones, who held sway long before recorded history, are stirring again-and they want this world back.
