The year is 3150. Centuries have passed since the Great War, a conflict that saw humanity fall to the might of vampires, werewolves, and witches. Now, the world is a patchwork of empires, each ruled by supernatural overlords. Humans, once masters of their own destiny, are now little more than property, their lives dictated by the whims of their powerful captors.

Rayne Carson, a young woman bearing a secret that could mean her very demise, finds herself an unwilling participant in this new world order. Her recent past is a blur of pain and torture, a year spent as a captive of James, the brutal Emperor of the now-fallen Dawson Empire. She was chained, beaten, and left for dead, her body a canvas of wounds and weakness.

Now, rescued by the enigmatic Adrian Harlow, Emperor of the Harlow Empire, Rayne is brought to his grand, imposing castle. As she drifts in and out of consciousness in the castle's infirmary, she hears hushed voices, feels the brush of warm blankets, and tastes the metallic tang of medicine. The world outside her immediate pain is still a distant, dangerous hum, but a fragile hope flickers within her: a chance to survive, to heal, and to keep her terrifying truth buried deep within her soul.
