When your best friend is a unicorn, every day is a stroll down the red carpet. Phoebe Howell's unicorn BFF, Marigold Heavenly Nostrils, is happy to provide the celebrity treatment—teaching Phoebe fancy new spells, giving her a ride to school so she doesn't have to ride the bus, and even negotiating with the tooth fairy on her behalf. But when Phoebe starts noticing that unicorns have become a trendy fashion statement, she doesn't feel quite so unique. Fortunately, she's distracted by adventures including a visit to the unicorn community and a trip to the woods to see her friend Dakota receive an unusual honor at the goblin award ceremony.
