Summary
A modern-day, AmericanUniversity!Hogwarts AU where Harry Potter is just an environmental engineer trying to keep on top of his classes and look out for his best friends.
This includes Hermione, recently converted to a math major by some dastardly Slytherin College of Arts and Sciences students. However, now that he’s popping over to the math building more frequently than when he was in math classes himself, Harry keeps running into Tom Riddle, a grad student who’s an intoxicating mix of charming, intimidating, and handsome (according to every student who’s had him as a TA anyways).
But can they actually work something out or is their romance destined to burn out as quickly (and confusingly) as it was ignited?
Can be read without Part 1.

Summary
Ginny: So. This guy. What does he look like?
Hermione: He’s. . . tall? And has kinda curly, dark brown hair?
Ginny: Hmm do you have any photos of him?
Hermione: Why in the world would I
Hermione: And based on a quick search, there’s a Theodore Nott who died aged 64 in Virginia back in 2014 and one who’s a classics professor in England, but nothing on the one here
Ginny: Well that’s disappointing. Get a photo of him if you get the chanceA modern day, AmericanUnversity!Hogwarts AU where Hermione Granger is a sophomore computer science student who Theo Nott is very interested in. For the potential of poaching her for the math department, obviously.

Summary
She blinks at the boy her age as he sits down on the bench facing hers.
“Hello, my name’s Justin Finch-Fletchley. I think we’ve met before. In the muggle world at some ball or garden party or something.”
Well, she hadn’t expected that. And here she was thinking that she’d successfully left behind the world of old money, peerage, and dancing at honest-to-god balls.
He did look kind of familiar though.
“Hermione Granger.”
***
As tagged, this is the story of the Platonic Only relationship between Hermione Granger and fellow muggleborn, Justin Finch-Fletchley. Both properly raised in muggle, upper class London Society, which means nothing to the snooty purebloods of the wizarding world.
(I know nothing about upper class London society circles. Or any upper class society circles. Except that there are definitely ones where stuff like cotillion is still a Thing.)

Summary
Sure, Tom Riddle was handsome and intelligent and well-spoken, but he was also two years her senior and completely unattainable (and also a Slytherin), and she was too practical to spend time lusting over a boy she could never have and and only superficially wanted anyways.
Then again, who said it was Minerva’s choice? -

Summary
AmericanUniversity!Hogwarts fics. Biased towards the math students cause there's three math degrees between the two of us ¯\_(ツ)_/¯ and they're specifically set in the late 2010's during the same years we were in undergrad, but that doesn't come up much. Might get added to every... uh... couple years... maybe.

Summary
Perturabo was very, very sick of being in this meeting. It was important to have meetings, he supposed, but that didn’t mean he had to like it. The air was thick with his brothers’ scents and it was giving him a headache. He just wanted to go back to his ship and take his suppressants and sleep until they kicked in and he stopped feeling so awful.
(Or, Perturabo gets "revealed" as an omega dispite him not intentionally hiding it)
(Or, a look at the different cultural views of a handful of Primarchs regarding omegas)
