Welcome to an enchanted land ruled by unicorn princesses!
Cressida Jenkins, a unicorn-obsessed girl who is sure that unicorns are real, is invited to visit, and readers will be thrilled to journey to the Rainbow Realm along with her! In each story, Cressida is called to help a unicorn princess and her sisters in a magical adventure.

When Princess Moon invites Cressida to the annual Starlight Ball in the Night Forest, she can't wait to dress up in her gown and dance the night away. But Ernest the blundering wizard-lizard casts a spell that vanishes the entire ballroom, and the only other available space is filthy--it hasn't been used in years. Will Cressida be able to find a way to decorate the old ballroom? One thing is certain, all the unicorn princesses will need to use their magic together!

This magical series is full of sparkle, fun, and friendship.
