These are no ordinary princesses — they're Rescue Princesses! Northernland is the snowiest kingdom the Rescue Princesses have ever visited. They are delighted to go sledding, drink hot cocoa, and make friends with the girl who lives there, Princess Freya. When Princess Freya's mischievous kitten goes missing, the princesses leap into action. They have to find the kitten — even if it means letting Freya in on their Rescue Princess secret.
