The Enchanted Princess Wakes

Once upon a time, a princess was cursed at her christening -- but not the one you heard of. When the fairy decreed that Rosaleen would fall into an enchanted sleep, and how she would wake, the grand plans of kings, to unite kingdoms, failed. They sent her to an out-of-the-way castle in the mountains, in hopes the curse would do no harm to anyone else.

There, alone, Rosaleen lived and learned, and realized that she herself had to be ready to face the curse, and when it broke.
