Summary
On his darkest days, Tom Riddle had written into his diary, "Sometimes, I wish I'd never been born." Ginny put the golden chain around her neck, like a hangman's noose. She took the hourglass in her hands, closed her eyes, and spun.

Summary
“And they’re calling him ‘The Boy Who Lived’? Mycroft asked.
“It’s quite a legacy,” Fudge defended.
Mycroft scoffed. “It’s quite a mouthful.” He watched as Potter’s eyes crinkled.Mycroft prided himself on his intelligence and his control. Right now he knew more than both British ministers and had control over two Harry Potters.
It was like Christmas, his birthday, and Easter combined.Series

Summary
Harry spends the whole summer before fourth year feeling restless. He chalks it up to the weird dreams he's been having, assuming Voldemort is responsible. And for some dreams, that's true - but what about the other ones? The ones that feel... familiar?
Back at school, things change one morning in September, when he and three other students wake up with the memories of the four Hogwarts founders in their heads. They don't know why they've returned, or how it happened, but they know one thing - they changed the Wizarding World before, and they're going to do it again. It's about time they shook things up a bit.

There's Something Different About Snape by a_decently_sized_worm

Summary
“Who are you and what have you done with Severus?” said McGonagall, her eyebrows almost disappearing into her hat. The query was meant as a joke, but there was a hint of legitimate doubt in it.
“I got therapy,” Snape blurted out.
༻✦༺
The year is 2025. An average guy gets hit by a car on his way home from work and dies.
In another universe, the year is 1992. Severus Snape wakes up. He proceeds to have a panic attack.
Yes, this is a silly, self-indulgent isekai/transmigration story starring Severus Snape (not quite a "self-insert"). Watch as he does shenanigans, has anxiety, and keeps putting everyone he knows into shock with his sudden tendency to smile. Get in everyone, we're gonna desecrate this world. Screw JKRowldemort—she deserves 0 respect for the way she uses her privilege to harm others just trying to live. Trans rights, mf.

Summary
A decade on from the Battle of Hogwarts, after ten years of the wizarding world thinking it’s safe, a serial killer emerges, leaving a trail of dead women in his wake.
Each of the bodies bears a gruesome encoded message for the Aurors… A message which - once unscrambled - claims the Dark Lord has risen again.
In the face of the mystery, the Order of the Phoenix is hastily reformed. Ron is stoic. Hermione is scared. Ginny is getting very good at putting on a brave face. Death Eaters who were never caught are getting ready to crawl out of the woodwork. And the Ministry of Magic has plenty of secrets of its own for Kingsley to worry about…
All Harry wants is to distract himself from a marriage falling apart at the seams. All Lord Voldemort wants is to get out of the horrible place between life and death.
So much so that he’s willing to agree to help his old enemy solve the case.
Or so he claims.
