Summary
It was the year 1998, and Wizarding Britain was finally beginning to heal from the wounds of the devastating war. Auror trainee Harry Potter was leading his first field operation when he was struck by a Killing Curse. This led to an unexpected encounter with Death, who revealed to Harry that he could turn back time to remedy his deepest regrets.
Unbeknownst to Harry, dark wizarding activities were erupting across Britain, threatening to shatter the fragile peace once more. But who was behind these sinister plots? What were they trying to accomplish? Was it too late to stop them?
Perhaps all the answers lay where Harry was headed...
This is a journey of family, friendship, self-discovery, and, as always with Harry Potter, a healthy dose of world-saving.
Inspired by Tsume Yuki's "Time to Put Your Galleons Where Your Mouth Is" and with her expressed permission, this is the author's fiction re-imagined.

Summary
Christmas 1979—danger, secrets, lies and their shared history looms large over the Blacks' first Yuletide season as a reunited family. While life as a fugitive proves bleaker (and more boring) than Regulus could have imagined, a botched espionage mission at Malfoy Manor draws Sirius deeper into the Black family web—and his cousin Narcissa's social set.
Meanwhile, Walburga hatches a daring scheme to restore her wild firstborn's damaged reputation in the family—finding him a suitable bride—while Orion grapples with the past, and the high price his two sons have paid for his inaction.

Summary
One kiss. One dare. One ruined reputation.
Bellatrix Black was never meant to fall—not for a Gryffindor. Not for him. When she’s dared to kiss someone at a pureblood party, she chooses James Potter. It’s supposed to be a statement. A power play. A warning.
He kisses her back.
It should’ve ended there. But at Hogwarts, hatred is safer than desire—especially when secrets bleed, reputations rot, and the person you loathe becomes the only one who understands you.
It was meant to be a game.
One kiss. One night.
But James Potter kisses like a challenge—and Bellatrix doesn’t know how to walk away.
Their secret could shatter everything.
She almost hopes it does.

Summary
“Well, you see, Sirius has been struggling with History,” – at this, Sirius made a contempt noise – “and we’re wondering if someone will be his tutor. Specifically, you. You’re the best in the year.”
“What?!” Remus gasped, the words leaving his mouth before he could catch them and reel them back in. “He’s, but he’s—”
“He’s what?” Flitwick asked, raising his brows.
“Conceited."─── ⋆⋅☆⋅⋆ ───

Summary
Sirius can't leave his goddaughter Harriet alone in the destroyed cottage, it's too dangerous, even if the Headmaster is probably on his way right now. But he also can't wait any longer, Peter's apparition trail is starting to fade, and he needs to catch the traitorous rat, needs to kill him.
But maybe there's a way.
Sirius' parents are dead, and Grimmauld Place is empty.
- "This is Harriet Potter, Dorea's blood," he said, watching his goddaughter, as Kreacher muttered something about mudbloods, "you will bring her to Grimmauld Place. You will treat her and care for her as if she was an heir of House Black."
Ok, good, she'll be safe there, and as soon as I'm done, I'll immediately pick her up and bring her to my home in Worcestershire. -
Harriet grows up with the Noble and Most Ancient House of Black. Well, really, with their portraits.

Summary
Harry Potter was the Boy-Who-Lived. The Golden Boy. The Chosen One.
But it turns out when you run head first into an unknown magical artifact and end up in a void, none of that matters. Now he's in a different time with familiar strangers who just can't seem to understand the new transfer student, Harrison Miller.
With a Defense teacher he can't let his guard down for a second around, the Marauders hounding the 'mysterious' new Slytherin, and his housemates who cannot fathom a muggleborn being among them, Harry has to wonder whether fate hates him or if he is really a trouble-making freak like the Dursleys always said.

Summary
If someone had asked Regulus Black what his biggest regret was, he would be caught between letting Sirius leave him behind in Grimmauld Place or becoming a member of a fanatical pureblood supremacist cult.
He had thought perhaps one day he could fix all of the words unsaid and apologies not yet given. But walking into a cave and drowning put a damper on that.
Until fate aligns and he finds himself back in 1975, the night that Sirius had run away and been blasted off the tapestry by Regulus' own wand. The night when everything had begun to tear at the seams, when Walburga and Orion Black had sold the spare to the Cause, a poor replacement for what the Dark Lord had been promised.
Regulus has to decide if he's willing to regret losing his brother all over again or else draw the wrath of both the Death Eaters and the House of Black.

Summary
“The Marauders aren’t something that will just go away once we graduate.” James continued, taking a more serious tone and addressing not only Remus, but the fear that they all had found recently in the back of their minds about what may become of them outside the walls of Hogwarts. “We’re a family. We’ve proven that again and again, haven’t we? We’re forever. Unstoppable. We’re infinite.”

Summary
Regulus Black miraculously survives the cave of Inferi. There isn't a single soul that he trusts, given that his brother is now locked up as a Death Eater Sympathizer and James Potter is dead.
James Potter.
The single most loyal person that Regulus Black had ever had the unfortunate luck to meet. He was annoying, and loud, and impossibly Gryffindor, but James would have done anything to win the war.
Even working with his best mate's baby brother, the real Death Eater.
A semi-dark, enemies to lovers, time travel, Jegulus tale without the guarantee of a happy ending.
