Phoebe and Her Unicorn: Phoebe and Her Unicorn, Volume 1 by Dana Simpson (Paperback)

The first book in this beautifully drawn comic strip series follows the unlikely friendship between a somewhat awkward girl and the magical unicorn who gradually shows her just how special she really is. Over a series of hilarious adventures, Phoebe learns to bask in the awesomeness of Marigold and discover just how extraordinary it is to have a unicorn for a best friend.
 
It all started when a girl named Phoebe skipped a rock across a pond and accidentally hit a unicorn in the face. Improbably, this led to Phoebe being granted one wish, and she used it to make the unicorn, Marigold Heavenly Nostrils, her obligational best friend. But can a vain mythical beast and a nine-year-old daydreamer really forge a connection? Indeed they can, and that's how Phoebe and Her Unicorn unfolds. Over time, Phoebe and Marigold acknowledge that they had been lonely before they met and come to truly appreciate the bond they now share.
