Cressida Jenkins, a unicorn-obsessed girl who is sure that unicorns are real, is invited to visit the Rainbow Realm. In Flash's Dash, the annual Thunder Dash is approaching, and Princess Flash has opened the race to non-unicorns for the first time ever! Cressida is the first human girl invited to participate, but Ernest the wizard-lizard accidentally casts a spell that covers the race track in sticky, pink goo! Join Cressida as she helps the princesses save the race. A fun story for the unicorn enthusiast early reader. The reader doesn't need to read book 1 to understand the story as the author writes a summary chapter of book 1 in book 2. ( )
