Redeem My Life Anew by accumulations_of_little_despairs (what_a_dork_fish)

Summary
Yuji's always been weird, but it's fine. He has lots of friends who love him dearly, who he loves in return. Okaan the krogan merchant, Ch'ch'kt the rachni engineer, Brute the tank-bred krogan, Kibou the revived geth, Aria T'Loak the Pirate Queen...
Well. Aria's less his friend, more his bloodthirsty auntie who trained him up specifically to be her pet gladiator. But that counts, doesn't it? At least she doesn't think he's a monster who needs to be put down, like the Alliance, nor does she think he's a disappointing failure, like Cerberus. Not that Yuji knows why Cerberus has any interest in him. He's just a normal Earthborn human. Right, Grandpa?
...Right?

Summary
Miranda Lawson wakes up in the woods, covered in blood. Battered. The place painfully reminds her of Earth, although she is unsure how she ended up here. Her weapons, armor, biotics. All gone. Her suit—torn to shreds. She’s bleeding out. The last thing she remembers is Commander Shepard’s arctic blue eyes upon awakening from the medical coma on the Lazarus Research Station. Upon arrival at the Minuteman Space station, she disappears without a trace, leaving a mystery for Jacob Taylor and John Shepard to solve while the time is running out—the galaxy is already silently burning from the stings of the Collectors’ swarms.
What happened to Miranda? Who is behind the disappearance, and what’s she going to do when Miss Perfect loses her superior biotic abilities? How is she going to solve it? How can Commander John Shepard help her and the galaxy if she is an unapproachable, difficult to navigate ice queen? And just what secrets the Illusive Man, and her father, Henry Lawson, are trying to bury from the rest of the world?
