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.

Summary
An oversight on the part of Dumbledore leaves Lily Evans dead, James Potter broken, and Harry Potter missing. But he seems to be concerned very little by it, seeing as in the end Voldemort was defeated and that was the goal.
With only a box of polaroids found shoved in the back of his closet as a clue, James has to find his son himself. But when he slowly starts putting the pieces together, he begins to realize that Lily and Harry aren't the only things Dumbledore stole from him.

Summary
"Tell me, Black, have you ever kissed a man before?"
When Sirius Black ran away, he left behind more than just a house, he left a brother to drown in the silence of Grimmauld Place.
James Potter has always been the boy who gets what he wants. He wanted the Snitch, he wanted the Cup, and for years he wanted the girl. But then he truly saw Regulus Black. Not as Sirius's little brother, but as someone strikingly beautiful and dangerously captivating. Regulus became the new, unreachable challange James could'nt ignore.
What starts as a reckless pursuit soon turns into a dangerous game of whispered promises in moonlit corridors and secrets that could burn the wizarding world to the ground. As Voldemort's shadow grows, James and Regulus find themselves caught between loyalty to their blood and the fire between them.
In a war where everyone must choose a side, they chose each other. But the price of choosing a Black has always been paid in blood.

Summary
Less than a week into the new school year, a loud knock disrupts the quiet of the fourth-year Slytherin boys' dormitory. The last person Regulus expects to find on the other side of the door is his (somewhat) estranged older brother, Sirius, his handsome face bloodied and bruised.
Even more shocking than Sirius's sudden appearance, is his request - if they'd be so kind, could he bunk with them in Slytherin 'for a bit'?
His brother's refusal to explain his abscondence from Gryffindor is irksome, but Regulus lets him in regardless, confident he'll unravel the mystery in due time. After all, Sirius has never been very good at keeping secrets from his younger sibling, and Regulus can be *very* persuasive when he wants to know something.
Unbeknownst to the Black brothers, however, their choices in that moment set off a chaotic chain of events that will have lasting repercussions for The Noble and Most Ancient House of Black, and change the trajectory of their lives for good.

James Potter is forbidden. Older, fierce, and wrapped in a scent that makes Regulus burn from the inside out. But Regulus can’t resist the pull, the hunger, the way James looks at him like he’s already claimed.
He knows it’s reckless.
He knows it’s dangerous.
But he’d bare his throat for him without a second thought.Bookmarked by MarShin4

Summary
Regulus Black considers himself a sophisticated individual. A perfectly normal teenager, really—despite what certain misinformed people may say about his attitude or his deep, abiding love for pettiness.
Not to brag or to inflate his own ego, but he would say he had adapted well to his role as a teenager in society. He has loyal friends (still annoying), helpful to those who need it (depends on what he can get back), and plays his role as a good son (for now). Even passing his OWLS with flying colors! (No lie there)
By all accounts, he is a well-adjusted, functional member of the community.
So where the hell did it all go wrong that he ended up with James freaking Potter of all people according to an insistent time-traveling teenager.
Or their own son from the future tells them to get their head out of their asses and angrily makeout or something

James Potter, who is entering his own rut. -
