Dear Twilight Sparkle,
I write to you from the Canterlot Historical and Nonfactual Generalist Educational Learning in Natural Gregariousness Society, having recently learned of your newfound position as head librarian of the town of Ponyville. While we are an organization of no great repute, we have recently begun to fund a number of subsidized book club programs in Canterlot under a literary endowment program. I'm writing to ask if you might be interested, in your capacity as librarian, in running the first such book club supported by us in Ponyville. Among other minor amenities, we are able to make monthly book selections available via mail-order at wholesale prices, and we have basic educational materials available for each book.
If you are interested, do reply and we will respond shortly to arrange the details.
Yrs. sincerely,
Liminal StateP.S. Next month's book is The Haunting of Hill Horse.
