Ice Magic by Yasmine Galenorn

Prince Karehl has captured Asajia in a treacherous betrayal, and now he intends to return home to Castle Eleago with her in his custody. Unaware that Asajia is in danger, Karehl’s brother Bran is on the run from the Prince’s guards, as he tracks down his loyal Riders of Lorani. And caught in the Snow Witch’s path, Bran’s cousin Fenling is attempting to save the Lorani from the icy grasp of the ice queen’s magic.
But Asajia finds hope in the midst of the long winter, and it promises to change her forever. But can she escape captivity before the prince carries through on his threat? And will the magic she discovers in the Bramble Fel forest destroy the bond between her and Bran?
