The legend of the first unicorn

"Once upon a time in Scotland, a young prince had lost his smile. It seemed nothing could raise a smile from Prince Donald, not the baker's treats or the bard's songs. The court magician tried to make a new magical beast for the prince, but it was so awkward he let it go. Hana, the magician's granddaughter, was still determined to help Donald. Using her grandfather's magic, she invented a majestic creature with the body of a horse and the horn of a gazelle, and called him 'a unicorn'. Hana and Donald playfully chase the unicorn through the forest, and it seems that this magical animal might hold the key to the prince's smile. But then they discover a darker beast, lurking in the trees"--OCLC.
