An immortal assassin. A terrorist threat. Nature under attack. Anadi is Primal, the 5th rider of the apocalypse, A true Force of Nature. Old and new enemies unite against her as she finally comes face to face with her creator. She knew that killing Azazel wouldn’t go unpunished—her past has a habit of coming back to haunt her—but this time they’re taking hostages. As Nature attempts to restore balance, a new Conquest has been chosen – the question is, which side of the scales will he be on? And who will come out alive?
