Displacement Effect by tijgersprong reviews
You know that odd feeling, that something is wrong but you can't put your finger on it? I have that feeling a lot, on an average of around two times a week. Usually its because I've forgotten to turn in an assignment for school, but right now I have a feeling that I'm not on Earth anymore nor in the year 2017. Why do I have this feeling you ask? Well the blue women did give it away

Awake by The Blocked Writer reviews
I woke up in a glass tank, stuck in a body that definitely wasn't mine, and that was just the first few minutes. Naturally it all pretty much went downhill from there.

As Luck Will Have It by jjpdn reviews
What's the odds of rolling three 6's in a row? 1 out of 216. What about the chances of tripping so hard you create a wormhole in the fabric of space? Lemme tell you, it's not even small number. IT'S ZERO. Sad thing is... I'm not even surprised anymore when this 'zero' happens to me more times than the 1/216. Welcome to my life, where everything is so coincidental it's stupid.

From How This Galaxy Turns by LyricalJelly reviews
Look, I expected a lot of things after my death but being reincarnated as Shepard isn't one of them. But I played Mass Effect.. so I should know what to expect right? WRONG.

Mass Luck by daReaper02 reviews
The fact that I was lucky enough to get reincarnated helps with dying. A new chance in a new world am I right? Of course, this new chance would be a lot less stressful if I didn't have to worry about the Reapers coming along and destroying it. I guess I'm going to have to help Shepard out with that won't I? Probably gonna have to, especially since I'm her sibling.
