Darkness. It was a strange and ominous thing. It creeped through every crack and absorbed the light. The murkiness was clouded and it filled Sunset Shimmer’s eyes as they slowly peered open. She looked around, dazed and confused on what was happening, and where she was. The smell of forest filled her lungs as she stood up slowly on her feet hooves. She paused, her hooves. She screamed, ’What?!’ She examined the rest of herself. “Oh no no no no, this can’t possibly be right!”

Twilight invites Sunset to spend a night at her house. Late night, Twi decides to read a story to her friend, but it seems that Sun isn’t paying attention to the story. Why was she looking like that at Twilight?

Rinnaul's review about it, check it out!

After months of hard rehabilitation from her new friends, Sunset Shimmer was slowly relapsing back to her old bully mentality that caused so much heartbreak many months ago.

What if ended up in another place helped her realize that she was slipping back to the dark side.

What if that place was home?

This story is a sequel to The Twin Students of the Sun.

Sunset Shimmer and Twilight Sparkle, along with Twilight's dragon son Spike, have finally moved to Ponyville! It's about a week after the Summer Sun Celebration, when they teamed up with their new friends Applejack, Rainbow Dash, Sweetie Drops, and Masquerade to save the world from Nightmare Moon's eternal night.

Now that they're (mostly) unpacked, it's time to catch up with their friends, meet the neighbors, and enjoy a welcoming party thrown by Dr. Pie, Doctor of Party-ology. And then Spike gets a message, containing the usual Grand Galloping Galla tickets. Ugh, so boring right?...girls? Why is everypony staring? Uh oh.

Episode 2 of the Sunsetverse, now open to more authors!

Sunset Shimmer had no idea why everyone was taking to this new girl so quickly. What does she have that she doesn't? Besides friends? And an endearing personality? And a cute butt.
