This story is a sequel to Kind Hearts & Coronets

“My name’s Daisy Jo Martinez. I was born – or so my birth certificate says – on March 30, 2012. I’m married with two kids, my husband’s a Naval officer. I’m originally from a town just outside of DC called Winchester, Virginia – apple capital of America, yay, go me. I’m a Republican – that tends to shock a lot of people – and I’m a practicing Catholic – and that tends to shock more people than the first, and like I said, I’m married – I think people start passing out at that point. I've lived a happy, charmed life and I’m proud to be an American.

“And as you can also see, I’m a pony. Well, physically anyway."

The first main story of The All-American Girl Saga.

There was no room in her heart for love, or so the song went. But love has a tendency to find a way, despite all odds.

At first, Chrysalis loathed him; the dumb-as-a-brick woodspony who goes by the name of Evergreen. But through circumstance, he is her only savior. And slowly, she comes to love the simple pony and his way of life. But her life as a changeling keeps holding her back. Will there be a happily ever after for them? Or are they doomed for failure?

This story is a sequel to The Best Night Ever

Final Arc - The Black Wedding
CH63 - If I Had a Heart
- The ponies of the Fourth Tribe are ascendant. Shining Armor hunts down his changeling "daughters," and even Lady Antimony won't get in his way. Meanwhile, high above the burning city of Canterlot, a long awaited reunion occurs, and Twilight confronts Alpha Brass and makes a final decision.

--- --- ---

It began with a mare from Ponyville and a time-looping Prince from Canterlot. This most unlikely union now stands at a crossroads: a ruthless changeling invasion; a conspiracy within the highest circles of the Equestrian aristocracy; a half dozen power hungry noblemares looking to become a Princess in all but name. With the prize of Canterlot and its Platinum Crown at stake, it falls to six Elements of Harmony to once again save not just Ponyville, but all of Equestria.

Someone out there made a playlist for Platinum Crown: Rarity, Blueblood and Chrysalis. Pretty sweet!
Wish I knew who, or even when they did it, though. I especially like the Chrysy playlist.
