This story is a sequel to The Fires of Friendship

Applejack is bitter about her lineage among the wealthy and sophisticated Oranges of Manehattan, who apparently abandoned her simple country family. Rarity is desperate to fit in with the urbane elites of the fashion world, even if it means disparaging and rejecting the Ponyville home she loves. On a trip to the big city for Equestria's famous Fashion Week, Applejack will teach Rarity to be honest and true to herself, and Rarity will show Applejack that a little generosity and forgiveness go a long way. Together, they will learn that each has exactly what the other needs to be complete.

This story is in the same continuity as "The Fires of Friendship," and I suppose it is a sequel of sorts, though there is no need to read that story first. More than anything, this story is birthday present for a dear friend, and a fun celebration of her favorite ship.

Hello, again!

Many ages after the original adventures of the Elements of Harmony, a certain dragon has his own role to play in the world. Strengthened by what they see as lacking, he stands apart from his own kin as they look upon him with both the fear and respect of one completely devoted to the destined task that he had been hatched for.

This story is a sequel to The Fruits of Their Labors

Rarity always believed that she knew exactly who she was, what she wanted, and exactly how she would obtain it. Then she fell for somepony wholly unexpected: Applejack. When unhappy tidings call Rarity to the frozen North to spend the Hearth's Warming holiday with her relatives, Applejack accompanies her into the family fray.

The ponies arrive in Whinnyapolis at a time of endings, and find that relationships can be fragile things, vulnerable to the cold. Rarity will search her past for the key to her future, but the old house at Maple Cove may not hold all the answers she needs. Perhaps, though, two ponies will learn that there really is no place like home for the holidays.

Due to an editing/publishing error, all of Twilight's friends have now 'officially' died of old age. This leaves an immortal Twilight to grieve over the tragedy of how she outlived all of her friends and will continue to do so for the rest of her eternal life.

Seeing the obvious pain that this news is having on Twilight, Princess Celestia moves to console her with the help of her supposedly-but-actually-not-really-deceased friends.
