A storm is brewing! And with Queen Haven away, the Mane 6 are the only ones keeping Zephyr Heights from being blown off its mountaintop. For the first time anyone can remember, Queen Haven is taking a vacation. She's decided to leave Zipp in charge of the royal palace in Zephyr Heights while she's gone, and as the crown princess, Zipp is confident she can handle the responsibility. She's not great at ceremony, but nothing really dangerous ever happens in Zephyr Heights anyway, right? Just to be safe, she recruits her sister Pipp and their friends Sunny, Hitch, Izzy, and Misty to come along. And it's lucky they did, because disaster is about to strike the capital!
