The Queen of Nothing
(Book)

Power is much easier to acquire than it is to hold onto. Jude learned this lesson when she released her control over the wicked king, Cardan, in exchange for immeasurable power. Now as the exiled mortal Queen of Faerie, Jude is powerless and left reeling from Cardan's betrayal. Opportunity to reclaim everything he took from her arrives in the form of her deceptive twin sister, Taryn, whose mortal life is in peril. But war is brewing in Elfhame. And, when a dormant yet powerful curse is unleashed, Jude must choose between her ambition and her humanity. -- adapted from jacket
