Brad and Twilight Sparkle are madly in love, so madly in love that Brad agrees to follow Twilight through the mirror portal to Equestria, where the two of them plan to have a big pony wedding. But when Brad comes to Equestria, he isn't a pony.
Twilight Sparkle arrives in Ponyville to prepare for the Summer Sun Celebration, and potentially the return of Nightmare Moon. All that stands in her way is five stallions who keep flirting with her. Making passes. Hitting on. You get the idea.
Shining Armor is Captain of the Royal Guard, and has no time for making friends. But when the Mare in the Moon threatens to return to the world, making friends may be his only hope to save Equestria.
Six stallions must use all their willpower in order to harness powers of Elements of Harmony and stop Nightmare Moon from casting an everlasting night.
