Prince Blueblood's 21st is approaching, and with it, his ascension to the throne. The only problem; he's a stallion. All of Equestria's leaders have been female. As have all their children, but for some reason Blueblood was born a male. Celestia thought she could overlook this by finding and teaching a suitable pupil, but Twilight Sparkle has created her own Empire in Ponyville and has no interest in moving back to Canterlot. So the sisters are left with one option if they ever want to retire; turn Blueblood into a mare.

Oh he may protest and hate the idea at first, but he doesn't have a choice, now does he, if she's to rule Equestria.
