Bryn Aven is an outcast among the Kanin, the most powerful of the troll tribes. Set apart by her heritage and her past, Bryn is a tracker who's determined to become a respected part of her world. She has just one goal: become a member of the elite King’s Guard to protect the royal family. She's not going to let anything stand in her way, not even a forbidden romance with her boss, Ridley Dresden.

But all her plans for the future are put on hold when Konstantin—a fallen hero she once loved—begins kidnapping changelings. Bryn is sent in to help stop him, but will she lose her heart in the process?

Hidden deep in the heart of a snow-covered wilderness lies the secret kingdom of the Kanin—a magical realm as beautiful as it is treacherous. Bryn Aven has never fit into Kanin society. Her blond hair and blue eyes set her apart as an outsider—a half-blood unable to hold a respectable rank. But she's determined to prove herself as a loyal protector of the kingdom she loves, even if it means confronting the traitor Konstantin Black, who once tried to kill her father.

It's up to Bryn to put a stop to him before he strikes again. But is she willing to risk everything to protect a kingdom that doesn't accept her for who she really is? And when her mission brings her closer to Ridley, will she be able to deny her heart?
