Ever had one of those days when you wake up to find you've accidentally switched places with your counterpart in a world where you and all your friends are stallions?
Looking for a way to get over her fear of public speaking, Sweetie Belle borrows an instructional book from Twilight's library to help out. One thing leads to another and some how ends up binding King Sombra to her as her shadow...
With Sombra threatening pony and changeling alike, Chrysalis and Celestia begrudgingly agree to an alliance. Neither is happy at first. Yet, as they work together, they discover lasting peace, and perhaps more, is possible.
Twilight panics when she discovers that Princesses are expected to have formal dates for Hearts and Hooves Day, so she travels to Celestia for advice, getting a lot more than either of them bargained for in the process.
Lovers have their reasons. To Twilight Sparkle, the reasons she loves Celestia are perfectly obvious. And to Princess Celestia the reasons why she can't love Twilight back are equally obvious.
