Sabrina's magical nemesis Amber Nightstone and her sidekicks, Jade Kazane and Sapphire Gill, are intent on becoming the most powerful witches in the world. Isolated from so many around them, the three have formed a coven based on their individual needs for vengeance and true freedom. But when there is some dissent among the ranks, their small coven is threatened to be obliterated from within.
