The Thessalonica LegacyThere, fixed up. They're in order of my favorite.
Sunset was very well written and the plot twists and intensity of the story were very good as well of the development of the characters.
Spark was good a bit hard to follow at times but still good.
Cupcakes, I just love the image of a psycho Pinkie Pie.
And The Thessalonica Legacy because of the action and the way the humans interacted with the ponies. It was long but overall a satisfying story.
