Meet Cloud Puppy! Her hobbies include making rainbows, super sniffing, and, of course, reading the Pretty Princess Warrior Dragonetta series with her best friend, Berry Rose. After Cloud Puppy finds out that her favorite author will be a guest at the local comic book convention, she and Berry Rose decide to attend in homemade costumes.

But when they both insist on dressing up as the same character, Cloud Puppy and Berry Rose have their first fight ever! Now, they're going to the convention separately. Will these feuding friends be able to make amends?
