In a world where every witch and wizard knows exactly the first thing their soulmate will say to them, Hermione's ignorance of that particular magical phenomenon was just another thing that set her apart. 

But when a ritual-gone-wrong tosses her back to the 1940s, she discovers the reason she never had the words her friends did. 

What's a girl out of time to do when her soulmate lived and died before she was born?




~Sneak peak from chapter 6~

"Are you familiar with the butterfly effect?"

He looked at her blankly. 

Right, though the theory existed, the term she was familiar with wouldn't emerge until the fifties or sixties. "The theory that a tiny event, the smallest of changes, can have far reaching reaching and drastically different consequences with each deviation from the original conditions."

Papilionem effectus (a Volturi Kings Fanfic) by ItskeLaufeyson

The butterfly effect; "How strange that even a very minor event, action or small shift can have such a tremendous effect. Like a butterfly's wing is capable of altering the path of a tornado. Certantainly everything, even the very thingy thing can effect everything." Or alternatively; How Bella's life could have gone if only the Volturi had met their mate earlier in their life times, and how she could be the butterfly in Bella's life. {Crossposted on ArchiveOfOurOwn under my username Acourtoffanficsandfeelings} {Bella x selfrespect} {MC x Volture Kings} {Canon Divergence}

Haunted Together by MissTeaDay

"Just get out of here, Hermione. I'll handle this myself." Draco hadn't called Hermione by her first name in... well, Hermione wasn't sure if he had ever used it in her presence. As he walked away from her, she noticed a limp in his step and a few droplets of blood trailing in his wake. With a sigh, she followed, her stubbornness getting the best of her. "Let me help," she repeated, quieter this time. "I'm sorry for what I said. Truly. You just--" "Bring out the worst in you?"

*•.~(Harry Potter x Fem! Reader) *** Harry had always known she was gorgeous, but this time she was breath-taking and he felt an awful feeling in his stomach when he realized she wasn't his anymore.

my bane, my antidote by acrazyslytheringhost

Harry Potter and Tom Riddle are something of an anamoly. Two powerful wizards, orphaned and linked to Death, while simultaneously being polar opposites. They are technically soulmates-the closest thing to it as they truly don't exist-and strange things are bound to happen. Especially when it's the soul of Tom Riddle is embedded into the soul of Harry Potter and the blood of Harry Potter is flowing inside the veins of Tom Riddle. What happens to one affects the other, whether they are aware of it or not, and they are bound irrevocably so. But the thing about Magic is that anything can happen with it-a mixture of blood magic, soul magic, and death magic is a recipe for all sorts of things. The thought of a pregnancy, though, never occurred in anybody's mind until it happened.

Baby, I've been running by MajorTomarryfan

Horror strikes him down where he stands, then. He sways, stumbles to put his back to the living room wall. Harry is woozy in disbelief, watching the two words slashed into his chest in livid red just like the scar on his forehead. 'AVADA KEDAVRA.' He knows those words, the first he can remember, his earliest memory. It feels like he hasn't breathed in minutes. When he comes back to the moment, he finds that perhaps he hasn't. Harry gasps for air like a fish does for water, and doesn't find it. His back has slid down the wall somehow and his hands grip his head, hair clenched in fists. Then he realizes he's actually panting, a ringing in his ears, blocking out whatever it is people are saying to him. Hermione crouches in front of him where he can't possibly miss her, palms settling gently on his knees. "Harry," she's saying. "Harry, it's going to be alright." How? How can it ever possibly be alright again? - In a world where the first words you ever speak to your soulmate appear once both soulmates have turned seventeen, Harry receives a bit of bad news. OR In which Harry fashions himself into a war bride. !Disclaimer!

It's a moment everyone anticipates with excitement... or dread. When Harry Potter wakes up on his 14th birthday, he expects to see Cho Chang or maybe even Ginny Weasley etched onto his skin. Instead, his breath catches in his throat as he stares at the name scrawled in dark ink: Draco Malfoy.

But when the name Harry Potter appears on his wrist, his world shatters. As tensions rise at Hogwarts and the Triwizard Tournament looms, Harry and Draco are forced to confront what fate has written for them. Is love truly written in the stars, or will they fight against destiny itself?

ELYSIUM • G. WEASLEY by -hellsqueen

"Seems like I've died and gotten to Elysium." The concept of soulmates in the wizarding world was one that had been present for a long time though few were the ones fortunate enough to find their own dear person. It is a forgotten concept, seems like nothing more than a fairytale to some, the dreams of children and immature adults who still believe in true love. Iris, being a muggle herself, was hardly even aware of the wizarding world, never mind its tales and lores, so the idea of a soulmate is one she doesn't believe in but finds intriguing still after reading about it. Until she meets George. Living with a person who understands you completely and is willing to love you for all you are truly feels like a dream come true. George has never felt luckier and with Iris by his side, even the abandoned tale of the soulmates seems possible when he thinks he could be experiencing his own personal paradise. NOTES: Anything but the plot, Iris and her family belongs to JK Rowling.
