This story is a sequel to My Little Pony: Friendship is Shining
When Shining Armor first came to Ponyville, he brought his sister with him. After the events with Nightmare Moon, Shining stayed in Ponyville while Twilight Sparkle went back home. Now Twilight is back in Ponyville with her parents to visit, and guess who wants to stay?
A story set in what I'm calling The Shiny-verse
