Arwen knows better than to face the ancient, wicked woods that surround the castle on her own, which means working with a fellow prisoner might be her only path to freedom. Unfortunately, he's as infuriating as he is cunning-and seems to take twisted pleasure in playing on Arwen's deepest fears.But here in Onyx Kingdom, trust is a luxury she can't afford.To make it out of enemy territory, she'll have to navigate back-stabbing royals, dark magic, and deadly beasts. But untold power lies inside Arwen, dormant and waiting for a spark. If she can harness it, she just might be able to escape with her life-and hopefully, her heart.
