Spellbinding and unexpected, Witch King’s Oath is a bold-hearted fantasy adventure packed with magic and intrigue, perfect for fans of Samantha Shannon and T. Kingfisher.  Magic and politics collide when Prince Anryn of Ammar survives an assassin’s blade at a witch trial gone wrong. On the run and desperate for help, he turns to Maertyn Blackfire—a lonely witch cursed with immortality by the mages of Nynomath, Ammar's enemy.  Stuck waiting for her missing prince, Beatrice feels she can do nothing but dance the nights away and dream of the day when she will be Queen. Then maybe she can do away with the repressive laws of Ammar. But her ambitions and her heart are pulled in another direction when she meets Ciamon Caelt—a mysterious man with a shared interest in discovering Prince Anryn’s whereabouts.  When a brush with Maertyn’s past awakens Anryn as a witch under a curse that hides a woman’s soul beneath Anryn’s skin, the prince is forced to question everything… including who her enemies truly are. Only at the altar where Beatrice waits can Anryn hope to uncover the plot, and save Maertyn from the fate the king’s laws decree for all witches: death at the stake.
