Spike does not like hugs. And he definitely does not like sleeping next to Twilight. At all.

A story of compromising and growing up.

Written for Everfree Northwest Scribblefest 2017

Ever wondered what Sunset does for a job? Mechanic, maybe? Computer analyst, perhaps? How about a waitress at a sushi bar?

Wait... what was that last one?

Silly little thing I came up with after the reveal of the "Sunset Sushi" Mini (which is utterly adorable!}

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

After nearly being mugged Twilight turns her considerable talent with magic towards self defense. When a fight with Luna goes farther that either of them wants it to, Twilight will need to find redemption in her new position as Luna's bodyguard and stop a conspiracy that wants to bring back a force more dangerous than either of them.

When the Cutie Mark Crusaders dig up an ancient magical artifact, they unleash a spell on the town that allows everypony to see a "lie meter" floating above each other's heads. While attempting to solve the mystery, Twilight Sparkle has to analyze the tenuous balance between friendship and honesty. She doesn't like what she finds.

This story is a sequel to Blinking

Teleportation. It is the best possible way to travel... As long as you don't think about it too much.

Twilight had saved herself from the teleportation curse, she would make certain that she was the final victim.

Fan sequel to Blinking by Lumberjack. Which was a fan sequel to Ocalhoun's Blink. Permission was given for me to write this. Hope everyone enjoys.

Today. Today, she would talk about it.

This story is a sequel to The Celestia Code

100% Approved by Twilight's Library!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!
