Thirteen-year-old Joy has a gift—she is extremely musically talented. That’s why after classes you can so often find her in Papa’s little shop, where he helps her study music. And one day, a mysterious visitor appears in the shop, wanting to sell Papa a horn through which enchanting music literally pours. But the horn costs too much; the visitor wants an enormous amount of gold. Yet the music, heard once, won’t let the girl go— it lures her into a magical land inhabited by unicorns and other fairytale creatures. But even in the magical land, not everything is calm. Joy worries about her new friends and tries to come to their aid. Joy learns that unicorns visit our world too, and some of them even live among us in the guise of people. Have you ever wondered if someone you know could be a unicorn?
