Hermione Granger and the Quest for Academic Validation by riomariyn
Fandoms: Harry Potter - J. K. Rowling

Summary
Hermione Jean Granger had been best of her year in every subject since pre-school, and as such, she determined it would be prudent to seek advance tutoring for her new school. If that meant following magical werewolves or wrestling trolls, so be it (better dead than expelled after all).
Nymphadora Tonks and Remus Lupin in no way intended to become the unofficial mentors of an 11-year-old muggleborn girl. They resign themselves to trying to drill a survival instinct into her head any way that they can.
Equipped with some (possibly illegal) hexes, some semblance of common sense, and ambition that could put Salazar himself to shame, Hermione sorts Slytherin.
What could possibly go wrong?

Books and Bitching with Harley and the Hood by riomariyn

Summary
As an ex-psychologist turned vocationally-obsessive-crazy-bitch turned reformed antihero (via the cleansing power of recreational marijuana and lesbianism), Harley knows a thing or two about psychoanalyzing. It was one of her favorite hobbies. In undergrad, she’d spent many a-night with fellow premed students (among them Brucie Wayne-- and don’t get Harley started on that guy), picking apart fictional characters, politicians, celebrities, and peers alike with speculation as to the origins of their truly baffling psyches. Alas, in her professional life, doctor-patient confidentiality had prevented her from sharing her thoughts with friends (not that she would have besides), and now her days as Dr. Quinzel lay behind her.
or
Jason finds himself inexplicably in a book club turned therapy circle with Harley Quinn. Yeah, he's not sure how this one happened either. But Harley is determined to force her new friend into emotional stability, happiness, and reconciliation with his estranged batfam if they have burn down the Gotham Barnes & Nobles to do so.

Summary
"average person breaks their nose once a year" factoid is actually just a statistical error. Regulus Black, a snarky idiot with an immensely punchable face who breaks his nose seven times a year, is an outlier and should not have been counted.
or
Sirius is getting seriously concerned with how often his little brother is getting his arse kicked, and brings him to Welton Academy's underground fight club. Somewhere along the line, Regulus falls in love, walks five miles through the mud, and kicks Lucius Malfoy's shiny white teeth in. Not necessarily in that order.

'cause you're just a man (it's just what you do) by orphan_account, riomariyn

Summary
During Regulus Black's first year at Hogwarts, he feels nothing but contempt for his stupid, troublemaking, Gryffindor brother, (who left him all alone in that cold, cold house), and his ragtag group of blood traitor friends.
As he grows (and gets kidnapped by said brother), he finds his contempt turned to begrudging tolerance and himself in a truely ill-advised relationship consisting of passionate trysts with Gryffindor’s golden boy, James Potter. Regulus knows that it won’t work out. That eventually, someone will get hurt. Still, James is the kind of hurt you lean into, addicted to the thrill of the flight right up until the fall. Maybe even still then.
Or
Reggie and James fight, then fuck.

Summary
Regulus Black has known he will drown since before he was old enough to put it into words.
He's never told anyone—not his friends, not his family, not his Divination professor, because a Seer is a powerful tool, and the last thing he wants is to be turned into a weapon.
But Britain is at war, and Regulus's secret is not as safe as he thinks it is.

Summary
Everyone always forgets about the Merpeople. So did Harry until the day his, Lee’s, and Hermione’s Portkeys land at Reagan National Airport’s Arrivals dais. He’s just had to leave a job he loves and pack his entire life—literally—into his luggage. Then Malfoy and his subplots arrive, and suddenly, saving the world again, one Mermaid at a time, sounds like the perfect excuse to do something he’s always wanted.
The one with mermaids and DC.
