It's Winter Break at Hilltop Academy and Lina couldn't be more excited. With time off from school, Lina's parents say it's all right for her best friend, Claudia, to come up to their cloud palace for a sleepover (as long as she double pinkie-swears never to tell the royal family secret!). Claudia can't wait to see what it's like to actually be a real princess!

But she soon learns that all the stuffy palace protocol isn't nearly as fun as it sounds.

The girls just have to get out and play! Claudia suggests they go down to the ground and have some fun with Lina's winter magic. They have a blast sledding and skating in the snow until an actual winter blizzard moves in. The girls are stuck on the ground, lost in the storm.

They will have to get resourceful, be brave, work together - and use Lina's magic in a creative way - if they are going to find their way out.
