Summary
Sam and Dean Winchester follow an impossible trail into a forest that shouldn't exist—and walk straight into a hidden world of magic.
Mistaking a group of Hogwarts students for demons, the hunters turn an already disastrous encounter into absolute chaos. Guns are drawn, wands are raised, older brothers are ready to kill each other, long-buried secrets come dangerously close to the surface, and Sam finds himself making increasingly questionable decisions where one infuriatingly composed Slytherin is concerned.
As mistrust gives way to reluctant cooperation, hunters and wizards must find a way out of the Forbidden Forest together. The only problem is that the forest has plans of its own—and getting out may be the easiest part.

It isn’t.
They are not the ones who woke up.

Trapped in a future that has no place for them, they must navigate a society built on strange abilities, unfamiliar rules, and relationships that don’t fit the lives they left behind.

Summary
A quiet afternoon in Los Angeles turns into something else entirely when Regulus Black’s past and present collide.
What begins as an unexpected gathering—old friends from England, found family from California, children, sunlight, and borrowed clothes—unravels into revelations no one was prepared for. Names shift. Histories resurface. Titles are uncovered. Stories spill.
And then, in the middle of it all, Regulus lifts his hand—and the world changes.
Because magic is real.
Because it’s been here the whole time.
And because some truths, once spoken, refuse to stay contained.Series

Summary
On a school day that was meant to showcase Muggle engineering, Hogwarts gets something else entirely: a phenomenon.
Regulus Black has never ridden a motorbike. He’s never driven a racecar. He’s never touched most of the sports laid out across the castle grounds.
He proceeds to master all of them in a single afternoon.
What starts as curiosity turns into spectacle, then into legend—drawing the attention of professional athletes, television crews, and one increasingly flustered racing prodigy who cannot stop staring.
Some people discover what they’re good at.
Regulus Black discovers everything at once.

Summary
In a town shaken by a string of brutal murders, no one suspects who’s really behind it all — or why. As the body count rises, secrets unravel, and deep ties of loyalty and love are revealed in ways no one could have expected. Some promises are deadlier than others, and in the end, it’s clear that nothing — and no one — is quite what they seemed.

Summary
At a glittering, suffocating Muggle awards gala, Regulus Black is counting the minutes until he can escape—until he quite literally collides with Justin Bieber, a boy too bright, too charming, and far too persistent to ignore. What starts as irritation in a quiet hallway becomes something sharper, stranger, and dangerously compelling.
Justin, used to a world that revolves around him, is fascinated by the one person unimpressed by his fame. Regulus, raised in control and cold precision, finds himself pulled into something messy, warm, and entirely unscripted. One conversation turns into stolen moments, stolen kisses, and a reckless decision neither of them can quite take back.
By the time the cameras catch them, it’s already too late. What was private becomes spectacle—what was accidental becomes undeniable. And somewhere between flashing lights, public chaos, and the watchful eyes of the Black family, something real takes root.
