The Book of Death: The Complete Series. The Book of Death

Death is not a force. It's a role. And someone is losing control of it. Ramona Knox has seen him since she was a child-a man in a suit who claims to be Death. Now an FBI agent, she's about to learn just how real he is. and how dangerous his mistakes can be. Because something is breaking. A plague tears through a fractured timeline. An immortal is forced to correct the past-by killing those who shouldn't exist.
Heaven itself begins to fracture under the weight of its own secrets. And as worlds collide, an ancient enemy rises to finish what was started long ago. Across shattered realities, collapsing afterlives, and the ruins of Earth itself, unlikely allies must come together to stop the end of everything-even if it means turning on one of their own. Collecting Leviathan, Underworld Earth, Atlas, and Apocalypse, this four-book set delivers a relentless blend of urban fantasy, dark fantasy, and cosmic horror in the explosive conclusion to the genre-defying saga begun in Olivia & Hale.
