After the early summer tourist trade produces an endless parade of traveling Canterlot residents who refuse to make a Ponyville purchase, Rarity decides to help the strangers in her shop -- help them buy absolutely nothing from her at all.
Celestia loves Twilight Sparkle. That is a fact, an indisputable constant of the universe. What that love means, however, is much less certain. The love of a teacher, the love of a friend, or the love that Celestia dares not name.
What does it mean to be immortal? Celestia's memory is very old. It is twisted and confused. She wakes one night to find that she can no longer tell her memories and her dreams apart. She no longer knows what was real and what was only dreamed.
The time for Twilight to succeed Celestia as Bearer of the Sun has come. But as the abdication ceremony in which Celestia will relinquish her power approaches, Twilight begins to desperately search for a way to stop the ceremony and save her friend.
