New Beginnings by AntonCheckOn reviews
Shepard thought that controlling the reapers at the end of Mass Effect 3 offered the greatest chance at bringing a lasting and happy peace to the galaxy, even if it cost her her own being. But it would seem that her story didn't end with firing the Crucible. This story is based on my other work 'Transitions', but is in a separate continuity. Rated M for violence, and language.
