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. In Prism´s Paint, Ernest the blundering wizard-lizard casts a spell that accidentally alters Princess Prism´s power--instead of being able to turn objects different colors, she now makes them clear! The only way to reverse the spell is to find the missing rainbow of the Valley of Light, and the unicorn princesses know who can help them: Cressida! But will Cressida be able to find the rainbow and restore Prism´s powers? This sweet series is full of sparkle, fun, and friendship.
