Melinoë, the only living child in the underworld spends a blissful childhood hearing stories of Gods and monsters, stories her father Hades has plucked from the minds of dead men who walk his kingdom. Her mother Persephone is often absent, forced to leave and honour a promise she made only to return in the winter, cold and indifferent to her only daughter.
But through the years, she begins to change. Her once luscious black hair is plagued with streaks of white, the weather seems to bow to every move of her fingertips and her nights are filled with monstrous visions of her mother, a man she does not recognise and the pain he caused them both.
As the foundations of her existence begin to crumble Melinoë learns a horrifying truth. One which will lead her to Olympus to face the root of her pain and existence.
After all, killing a God may drive you to madness.
