"After transferring to Canterlot High, Twilight Sparkle has a lot to catch up on. It's not doing homework that the super-smart student is worried about, though: it's being a friend! With Sunset Shimmer, Pinkie Pie, Rainbow Dash, Rarity, Applejack, and Fluttershy all eager to embrace their new classmate, the transition should be a breeze. But, as Twilight Sparkle is always down for some extra credit, she seeks guidance from some familiar faces from Crystal Prep. Unfortunately for Twilight, these girls haven't always had the best intentions. How will Twilight Sparkle manage to have fun at her first sleepovers with bad friendship advice?"--Provided by publisher.
