Katie the unicorn had a very special horn. Her horn was magical. It twinkled by day, and it shone brightly in the night light. When Katie looked up to the sky, her horn would catch the rays of the sun in the day and the light of the moon at night. Androna, an evil queen, had always wanted Katie's horn. She would look with envy from her castle tower as Katie danced under the moonlight. Will Androna succeed in getting Katie's horn?
