The Faerie King has entered into a pact with the demon lord, trading his people’s freedom for the might to conquer the nine realms. Two unlikely allies are determined to stop him: Asherah, enslaved by demons, and Caol'nir, a warrior sworn to defend the king. When Asherah, stripped of both her memory and her dignity, learns that King Sahlgren is responsible for her captivity, she leads her fellow slaves in a daring escape and burns their prison to the ground. Then she learns that there are many more prisons across Parthalan, and embarks upon a campaign to free every last faerie. In stark contrast to Asherah’s struggles, Caol'nir lives the comfortable life of a temple guard. He is sworn to serve and defend the king, as his ancestors have done since time immemorial. Now a priestess has been murdered, and Caol'nir learns that Sahlgren’s scheming is to blame. Determined to thwart the king, sacred oath or no, Caol'nir joins Asherah’s rebellion. What Caol'nir doesn’t know is that Sahlgren has promised the demon lord a woman of rare and singular beauty, a woman who is rumored to be the sun god’s daughter. She also happens to be Caol'nir’s mate.
