Mordizan

The bane of Mordred, the son of Mordizan, and a millennia-old prophecy. 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.
As Brinnie navigates court intrigue, battles, and ominous new depths to her own power, she struggles to draw the lines. How far will she go to destroy Mordred? And how much of herself is she willing to give up along the way?
