Saoirse has one task after being Bound to the king who murdered her mother: hunt down other members of her kind and anyone who dares to help them. For fifteen years, she's been his unwilling faie spy. If her next mission doesn't kill her, the guilt might.
When the king's son offers her a deal-investigate a series of attacks on magical beings in exchange for her freedom-Saoirse reluctantly agrees. She knows better than to trust a royal, even one who claims to want his father overthrown. But she can't walk away from a chance at freedom.
She joins the prince and a band of allies, including a charming lieutenant and a Bonded faie she despises. Drawn to the lieutenant, she struggles to ignore the Bonded, even though he seems to be the only one who understands the darkness growing inside her. But the truth behind the attacks is far more sinister than they imagined: a forgotten god of shadows is rising, calling to the silver shadows that mark Saoirse's skin.
Now, Saoirse isn't just fighting for freedom-she's fighting to survive, and for a realm she may not be able to save... or want to.
