My protector is gone, revealed to be a monster. But I remind myself that I am not a damsel. I'm no princess bound within a tower.

I am a shadow.

Vasalie Moran was once a dancer in King Illian's court, until he framed her for murder. Barely surviving her two years in the dungeons, she's suddenly called to face her king. He offers her a deal: become his spy at the monthlong royal Gathering and he'll grant her freedom.

As Illian's orders grow bloody and dangerous, forcing her to harm and betray those around her, Vasalie discovers that the monster she serves may be aligned with a bigger monster--one far closer to home. With her world threatened, Vasalie enlists the help of Illian's brother and greatest adversary, the infamous King of the East.

As the rivalry between brothers escalates, with Vasalie caught in the middle, the horrifying truth of her past comes to light. If she wants to survive, she must decide who to trust, who to fight for, and how much of her soul she's willing to damn in the process.
