"When you stare into the abyss long enough... sometimes it stares back with familiar eyes." - Friedrich Nietzsche
The walls of Quantico have held killers, spies, and the darkest minds the FBI has ever profiled but never someone like Seraphina Fairchild.
Found at the scene of a brutal murder. she's brought for questioning. Calm, composed, and uncooperative, Seraphina seems more soldier than civilian. Every question from the BAU meets a carefully constructed answer too careful for someone who's supposed to be in shock.
Dr. Spencer Reid can't read her. She doesn't fit any known pattern no psychosis, no trauma response, no lies he can prove. Yet there's something off about her eyes, the way she moves, dna traces that don't match any record.
While the team hunts for a supposed serial killer, Seraphina hides a truth no one is prepared to face: the murders aren't human. And if she can't contain what's coming, neither will they.

"Nephilims" That's what they're called, beings that protect the mundane world from demons, beings that are half-angel and half-human. They only have one task, and that's to keep all demons at bay until the time arrives where they can slaughter all demon-kind. Ophelia Morgenstern is a shadowhunter who can't seem to get through a day without making a sarcastic remark. She's undoubtedly one of the best at what she does, but she's also the daughter of the most wanted man in the Shadow World. Alec Lightwood is a brooding shadowhunter with the tendencies of following the rules no matter what. He basically lives his life on the saying, "Sed lex, dura lex." which means "The law is hard, but it is the law." They've known each other for practically their whole lives, and they have always felt a burst of emotions around one another, but with the arrival of the "new" shadowhunter, their whole world flips on its back. With everything that's going on around them, will they gain sight of the feelings they truly have for one another?

HOUSE OF CARDS | Spencer Reid
'𝘤𝘢𝘯'𝘵 𝘧𝘪𝘯𝘥 𝘺𝘰𝘶𝘳𝘴𝘦𝘭𝘧, 𝘭𝘰𝘴𝘵 𝘪𝘯 𝘺𝘰𝘶𝘳 𝘭𝘪𝘦.' Spencer prides himself on his ability to detect lies, to spot the tiniest inconsistencies in a person's story - it's the one thing he's always been able to rely on. Which is why he feels such a disdain for the BAU's newest member. Unlike the rest of the team, he isn't fooled by her veneer of normalcy. There's something off about her; a lack of warmth in her smiles, a lack of light behind her eyes... She's hiding something, he knows she is. He just needs to prove it, and her 𝗵𝗼𝘂𝘀𝗲 𝗼𝗳 𝗰𝗮𝗿𝗱𝘀 will come crashing down. [ A Spencer Reid x Reader ]
Psychopathy
(A Criminal Minds Fanfic {Dr. Spencer Reid}) Book 2 in the "Psychosis" series. As long as the members of the BAU have known her, Ciara Byrne has kept a wealth of secrets- secrets that seemed to destroy her even as she held tightly onto them. After a year of working with her, most of them had learned to let it go and had given up on ever finding out those secrets. But when Ciara goes missing, letting those secrets stay hidden may not be an option anymore. Dr. Spencer Reid thought he knew Ciara. But as the investigation goes on, more holes start to appear in the plot of her life, and he starts to realize how little he actually knew her. But what he did know was that her disappearance left him realizing how much his feelings for her had grown and that he should have told her that long ago. He knew that the key to finding her before it was too late was hidden somewhere in the secrets of her past, and when the genius set his mind to something, nothing and no one could stop him. The clock is ticking. An agent's life is on the line. And if the BAU wants to have any chance of seeing Ciara again, they'll have to work hard to unearth the secrets she fought so hard to keep buried. *Rated Mature for scenes depicting sexual assault and graphic tortureComplete

Statistical Probability Of Us
When twenty two year old Charlotte Quinn joins the BAU, she's ready for anything-except the relentless pace of the nation's most elite profiling unit. Brilliant, composed, and fiercely determined, Charlotte has spent years proving she belongs here. What no one at Quantico knows is that she's also a single mother to a four year old girl named Estella. Except her childhood neighbour and a person who was always like a big brother to her, Aaron Hotchner. Keeping that part of her life hidden is easier than she expects-until she meets Dr. Spencer Reid, the young genius who reads everyone except her. At twenty three, Reid is as brilliant as he is awkward, a prodigy who sees the world through numbers and probabilities. But when Charlotte joins the team, equations start to fail him. She challenges him, steadies him, and somehow makes the chaos of their cases feel human again. As the BAU hunts monsters across the country, Charlotte and Spencer find themselves drawn together in ways that defy logic. Between late night case files, quiet conversations in hotel hallways, and unspoken secrets, a fragile bond begins to form-one that could unravel everything they've worked for if it ever comes to light. Because in a world built on patterns and predictability, love is the one variable no one can control.
