The bane of Mordred, the son of Mordizan, and a millennia-old prophecy-together they may provide what Brinnie needs to defeat the world of magic's greatest threat.

More than a year has passed since Brinnie left Wraithwood, never expecting to see it again. But when Mordred captures her sister, she is thrust back into the world of magic. She flees to Wraithwood, where she learns of a prophecy located in the dark wizard capital of Mordizan that reveals the identity of "Mordred's bane," something that could destroy Mordred for good.

Brinnie agrees to a rendezvous with Mordred to exchange herself for her sister, going undercover at Mordizan as a spy to find the prophecy and Mordred's bane. There, she weaves a complicated web of secrets, lies, and tenuous friendships. She makes an unexpected ally in Marcus Vorath, son of the Master of Mordizan, who fears the implications of Mordred's growing power. But in Mordizan, friends and foes may be one and the same.

In the midst of court intrigue, battle, ominous new depths to her power, and searching for Mordred's bane, Brinnie struggles to draw the lines. How far is she willing to go to destroy Mordred? And how much of herself is she willing to give up along the way?
