Princess Minna lives in Castle Tall-Towers with the King and Queen, Raymond the Wizard and her best dragon friend, Lorenzo. There are often mix-ups and mishaps in the kingdom and Princess Minna loves to sort them out! She can tame unicorns, kiss frogs and fight dragons (apart from Lorenzo) and she is very good at fixing things before it's time for bed.

In The Unicorn Mix-Up, Princess Minna is so tired she gets a bit muddled and fights a unicorn, kisses a dragon and tries to tame a frog - which won't do at all! Can she sort it all out and make a new friend along the way?
