1592. Cybil Harding, daughter of a secret alchemist, was born under cursed stars. Destined to bring disaster to those around her, Cybil is trapped in a grand house with a mother paralysed by grief and a father willing to sacrifice everything in pursuit of magic.
Miriam Richter is a creature born of shadow. Forged by the dark arts, she is doomed to exist for eternity and destined to be alone consuming the souls of mortals for sustenance.

Everything changes when Miriam meets Cybil, whose soul shines with a light so bright, she must claim it for herself. Miriam offers a bargain- she will grant Cybil reincarnation and the chance to change her stars in exchange for her soul.
Thus begins a dance across centuries as Miriam seeks Cybil in every lifetime to claim her prize. But Cybil isn't inclined to play by the rules. As the two women circle each other, drawn together inescapably as light and dark, the bond forged between them grows stronger. In their battle for dominance, only one of them can win - but perhaps they can't survive without each other.
