When they are found in a universe on the precipice of their own history, the meaning of the term "Mass Effect" will change forever.

Sense and Flexibility
by Roarkshop reviews
The story of Garrus and Femshep as told by me. Lots of off-canon. Sequels incoming. TW: It's been brought to my attention that some of Garrus' more animalistic behavior in some scenes have caused panic attacks for victims of abuse. I am so sorry for anyone who had a similar reaction. SO sorry. I would like to make any new readers aware of this beforehand. Thank you.

A short story depicting Commander Shepard in a mission set with an asari commando squad. Own characters used, and no, I do not own Mass Effect, or receive benefits from telling stories. So there. Rated T for innuendo, and that I have no clue what the rating system here mean. Let me know in a review or PM, eh?
