C-Sec: The Thin Blue Line by DarthBubbles
Fandoms: Mass Effect Trilogy, Mass Effect - All Media Types
01 Dec 2025

Summary
Zakera Ward is chaos, and no one knows it better than rookie C-Sec officer Leila Dawes. Born and raised in the Citadel’s darkest corners, Leila's past is one she'd rather bury - especially now that she's wearing a badge. But surviving gang wars, dirty politics, and ruthless criminals as one of the newest rookies on Captain Armando Bailey's squad means confronting secrets she swore she'd leave behind.
The last thing Leila expects -or needs- is to clash with Jace Wilcox, a former soldier whose rigid sense of duty challenges every reckless instinct she has. But alongside their fellow rookies, including an academy standout born into a legacy C-Sec family, a brilliant tech specialist who's seen the system fail one too many times, and a former merc with one foot out the door and nothing to prove, Jace and Leila uncover a conspiracy larger than anything they've trained for: an unseen enemy pulling strings from the shadows, threatening to unravel everything Commander Shepard once saved.
A gritty Mass Effect crime procedural about found family, dangerous loyalties, slow-burn romance, and the five rookie culprits behind Captain Bailey's constant headaches.

It's up to Second Class Major Crimes Detective Castis Vakarian and his new partner - the newest addition to the Major Crimes team - to piece together both how and why someone would kill the beloved veterinarian before the rapidly cooling trail can be erased entirely. But if anyone does know why someone would harm the sweet-natured elcor, they're being kept quiet by fear, apathy or some combination of the two.
Only, the situation is set to become all the more complex as Castis' personal and professional lives are forced to collide explosively - and left with his reputation on the line twice, he finds himself betting pride, reputation and relationship on a longshot; that he can solve this one case. -

"Vakarian!" She's practically crowing. He's only met her once, but she's hard to forget, so he can imagine the scene: Shepard, loose and long-limbed, sprawling sideways over her pilot's chair, her strange, human mouth in a wide, triumphant smile. "Of all the transport lanes in all the universe – "

Summary
Lauren Shepard was raised in an orphanage on the Citadel. When she turned twelve, she ran away from said orphanage, thinking that living on the streets would be better.
It wasn’t.
That is, until someone took notice of her, and invited her back to the Xirid District Reds: a gang that operated primarily in the Xirid District on the Bachjret Ward of the Citadel. Their specialty: drug dealing, armed robbery, kidnapping, extortion, and theft.
Curt Weisman, the leader of her particular group, took interest in her and became her on-again/off-again boyfriend soon after she joined the gang. Curt taught her the ropes, both in the art of theft and sex, toxic as it may be.
Early on, Lauren had quite a few arrests on her record, all by one particular cop. Now at nineteen, Lauren has improved her thieving abilities throughout the years, until she is once again taken into custody by Citadel Security.
