The Mane Six have left Ponyville for the summer, each traveling to a different part of Equestria for different reasons. But a few months and a little distance can't stop their friendship!
This book collects the letters they send back and forth, telling each other about the new places they go and new ponies they meet, comforting each other when they get lonely or homesick, and keeping the spirit of friendship alive.

Rarity and Fluttershy have been friends for years, and every week they go to the spa. But after every trip, Rarity finds herself growing greener with envy over Fluttershy's beauty and grace, if not something more than just envy— and what might happen if she finds out Fluttershy feels the same way about her?

Couples go through rough patches all the time. But what do you do when you have two marefriends, and you know you're bad with words?

This was written for the polyamory challenge over in the Shipping Discussion Group.

Enjoy.

Fluttershy spends the day with her two girlfriends, but she feels a quiet discomfort. As an asexual mare, she can't join in on everything Rarity and Twilight do together. Is she really good enough for them, or is she just bringing their relationship down?

My first purely fluff story, without much comedy. Just warm feelings.

Applejack, Twilight, and Rainbow Dash really enjoy each other's company. So much so that some ponies are beginning to wonder about them. Twilight and Applejack are a couple after all, so its a bit unusual that Rainbow always seems to be invited along. But sometimes, a couple is more than two.

Like a first date.
