When Cassie was little she thought her mother had been taken prisoner by
trolls because of a deal she'd made with the Polar Bear King. Just a
fairy tale to soothe a child whose mother had died. But on her
eighteenth birthday, the "fairy tale" comes true when the Polar Bear
King comes to take Cassie for his bride. Realizing she has the power to
save her mother, Cassie makes her own deal with the bear and finds
herself on a journey against time, traveling across the brutal Arctic to
the land east of the sun and west of the moon. It is a journey that will
teach Cassie the true meaning of love and family--and what it means to
become an adult.
