Being best friends with a unicorn is truly incredible, as 10-year-old Phoebe Howell knows from experience. But what would it be like to actually trade places with a magical unicorn for a day? As it turns out, it's much harder than it looks! Phoebe's botched muffin spell turns the sky plaid. And things aren't any easier for Marigold Heavenly Nostrils, who has no idea how to hold a pencil. The friends also meet a three-eyed flying creature named Glorpie...

"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...

Follow Phoebe and her unicorn, Marigold, as they experience somewhat-spooky Halloween parties, ecstatic snow days, and looming summer reading assignments. Although the journey of growing up can sometimes be difficult, along the way Phoebe and Marigold discover something more enduring than goblin fads, unicorn spa vacations, and even a Spell of Forgetting--their one of a king friendship.
