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!

A brand new, fun filled chapter book series that answers the question: What if Frozen's Elsa went to regular school?
