Summary
"Why would I drink from this bag," James purrs, "when I have you, sweetheart? My willing little living blood bag."
Heat floods Regulus' cheeks, shame and desire tangling in his chest. "I'm not—" he starts, but James cuts him off with a finger against his lips.
"Aren't you?" James whispers. "You came here willingly. You knew what I am. What I do." His fangs descend, tracing the line of Regulus’ throat. "Your heart is racing, little star. Is it fear... or anticipation?"
Or: James Potter is an ancient pureblood vampire—gorgeous, powerful, obscenely wealthy and, most dangerous of all, bored. He finds his newest entertainment in the worst possible place: taking wicked delight in corrupting vampire hunter Sirius Black’s younger, painfully innocent brother, Regulus.

Summary
In Regulus’s defense, he doesn’t mean to turn James Potter into a vampire.
His plans are much simpler than that. He only intends to abduct the boy who has led his brother astray, have some fun torturing him for a week or two, kill him, then dump the body on Sirius’s doorstep. Maybe carve ‘from RAB, with love’ on his chest for dramatic effect.
See? A nice, straightforward plan.

Summary
Vampires are the most loathed creatures in all the world. For centuries, they brought death and bloodshed upon every living being, and as a result, after a long, gruesome history of violence, they were imprisoned within their own land by powerful magical borders, ensuring their cruelty could never touch another soul again.
But what happens when those borders fail to hold, and two fugitive vampires find themselves crossing into the realm of their ancient enemies?
Is it a flaw in the magic that binds their world… or a destiny long foretold?

Summary
Centuries ago, the Black family made a pact with something ancient — a god without name, buried beneath the house in pieces. Magic sealed it. Blood fed it. And over time, even the family forgot.
But Regulus Black remembers. Or what’s left of him does.
He returns from the dead tethered to one fragment of that god, starving and unraveling. James Potter can’t stay away. Sirius can’t destroy what’s already inside him. Peter hears the pieces waking. Remus feels the house begin to shift.
Rooms warp. Dreams bleed. The god is stirring again.
And when it rises, someone will have to bleed to stop it.
_______
“You came here thinking this place was safe. But you think the house itself might be part of the god’s grave.”
Regulus nods. “If I’m right, then we were raised on its bones.”
Sirius laughs. Not because it’s funny. Just because of course. Of course.
“Brilliant,” he mutters. “A cursed god buried in the basement. How very Black of us.”

Summary
He froze hearing that name. James Potter. The name of the man his family expected him to be with. The man they carefully constructed an entire persona for. A man he shouldn’t have met in the back room of a cleverly disguised brothel. “What did you just say?” he spluttered.
“That’s my name,” James told him. He grinned, clearly amused by his flustered state. “James Potter.”
_______It's the 1920s James is a vampire. Regulus owns a burlesque club. Barty is unhinged.

Summary
In a world at war—where humans battle the supernatural—fifteen-year-old Regulus Black has always been an outsider. Pale, quiet, and drawn to the dark, he’s long been mistaken for the very creatures his family is sworn to hunt. But Regulus isn’t a vampire. He’s a vampire hunter—descended from a powerful bloodline that has fought monsters for generations.
James Potter is everything Regulus isn’t: bright, golden, and adored. At seventeen, he’s the best friend of Regulus’ older brother, Sirius, and the last person anyone would suspect of hiding a deadly secret. Because James is a vampire—and he’s falling in love with the one boy raised to destroy him.
As tensions between humans, vampires, and werewolves reach a boiling point, Regulus and James must decide what they’re willing to risk for each other. With the reluctant help of Sirius and a sharp-tongued werewolf named Remus Lupin, the unlikely group sets out to uncover the truth behind the war—and to stop it before it costs them everything.
A forbidden love. A deadly legacy. A war only they can end.OR

Summary
That’s when he saw him.
Leaning against the damp brick wall of the entrance, a handful of students hovered nearly, never getting too close, but laughing loudly, eager for his attention. Regulus didn’t realise he slowed his pace, watching the boy carefully. He was apart from them - an outsider - and as Regulus stared, it was as though his vision blurred around the edges, while the man remained defined.
His dark skin caught what little light filtered through the clouds. He wore rounded glasses which sat firmly on the bridge of his nose. His coiled hair lay perfectly, despite the slight drizzle, a clear contrast amongst the rest of the cohort, who were each drowning incrementally under the fine rain. The air seemed different around him. More alert.
Their eyes met, only briefly, and the oxygen in Regulus’s lungs momentarily halted.
Gold. Not hazel, nor brown, but gold, and bright enough to disorientate Regulus momentarily. He felt his heart in his throat and had an urge, running deep within him, to look away. And yet, he couldn’t. His feet refused to move, and the boy’s gaze was holding him down.

Summary
The anniversary of Regulus and Sirius’ parents' death is today.
One year ago, the Black family car veered off the bridge and into the lake. Two died. Two didn’t. Regulus doesn’t remember the crash, just the sound of his head slamming into the seat in front of him. Then, nothing. Until Sirius pulled him out of the water, screaming.
