When a blizzard threatens the unicorns' days in the sun, their Queen, Goldenmane, performs a magical transformation to help keep her herd safe. Alone, she searches the world for a new sunny meadow that the unicorns can call home and where they can be reunited once more. Will she find the green grass and blue skies that she's searching for? And if she does, how will she call the transformed unicorns back to her? Her brave journey through the cold reminds us all that loyalty and love for our friends can take us on greater adventures than we were ever expecting.
