Snow Bound by C. J. Brightley

Ice goblin magic, an enchanted prince, and a peasant girl with nothing but courage and compassion

Life in the North Lands has always been hard, but this winter is the most desperate Gytha has ever seen. Her family is desperate for any help.
Even from the enormous white bear.
Alexander offers food and kind words in his deep, growly voice, and Gytha cannot help but trust him. Even if he does have long, white teeth and claws.
But what he asks in return for his help will test Gytha’s very soul. For a year and a day, she must endure loneliness and isolation in the prison of the ice goblin queen, without letting the queen’s twisted words or the uncanny, silent goblin servants break her determination or her faith in Alexander.
What if Gytha’s courage and compassion are not enough to overcome the ice goblin queen’s magic?
What will it take to free the bear prince? Gytha, and the friends she has made in the frozen North, will not rest until they find out. Courage is not real until it is tested.

What will come will test them all.
