    Summary

    Harry has always been eager to learn, but his childhood with the Dursleys shackled his innate imagination and curiosity. Days after his eleventh birthday, he discovers a world far more magnificent than anything he could have ever imagined. There, his mind and abilities freed, he will meet new friends, learn the elegant art of magic, and, possibly, face powerful, sinister enemies.

    Summary

    Severus Snape has a friend. A grumpy bitch of a friend with a scowl to match his own, a punk attitude, and a dark sense of humour. How will his character arc be changed by having a co-conspirator who won't take his shit, but will give him a hug?

    I plan to rewrite the entire series with the inclusion of my O/C. This first part is a prequel & first year, spanning 1986-1991, but including some flash backs to 1980.

    Petronella Blishwick attended Hogwarts in the marauders era, was damaged by the war, and though gifted with charms never found her way in the world. When an old friend shows up to bring her back to the Wizarding World it will change the course of all of their lives.

    There will be laughter, tears, teen angst, teacher angst, emotional highs and lows; as characters and their relationships are changed and tested. All rolled up with plenty of acerbic comments, dry humour and kick ass magic!

    Expect some emotional Snape & Harry moments towards the end to set up for a closer relationship between the two in the future... plus some fun and cute Draco moments.

    Short character bio in the notes at the bottom. Enjoy!

    The Dark Lord did not expect Lady Malfoy to solve a 50-year-old cold case.

    Possibly reaffirm his suspicions, but it would be a long shot.

    Lucky for him, Lady Malfoy does not see failure as an option.

    Summary

    Sure enough, not five seconds later, the door cracked open, and a tall boy with green lining on his robes strode into the Hospital Wing. Hermione absent-mindedly noticed his attractive face, but she was more focussed on his uniform.

    Lord, that looks stuffy, was her first thought.

    At least he knows how to tie a proper Windsor knot, was her second.


    Hermione wakes up in 1943 alone, annoyed, and uninformed.

    And why the hell was life so determined to pit her against Tom bloody Riddle, anyway?

    Summary

    Harry Potter has made a very successful career for himself as an Auror but, despite being offered promotion to Head Auror after working himself to the bone at the cost of his personal life, finds that he's not even sure if he's on the right path. When an unexpected offer comes to take up the DADA position at Hogwarts, he thinks he might be able to finally find a proper fit for himself. However, something terrible is brewing that even he might not be ready for without additional Dark Arts training, and the only one that might be able to help him is Severus Snape.

    Summary

    At the end of his life, Harry is given the chance to alter the course of the dark reality his son Albus and Albus' friend Scorpius create when they use a Time-Turner to save Cedric Diggory's life. With the hindsight bestowed by a lifetime as Auror, Head of the DMLE, husband, father, and friend, he will make very different choices as a seventeen-year-old wizard to try and save the people and the world he loves.

    But if he has to do it all over again, simply defeating Voldemort won't be good enough: there's a never-ending scroll of tragedies to avert and one newly-installed Headmaster of Hogwarts to talk around (if he manages to get a word in edgewise before getting hexed). The good news is, as always: he's not fighting alone.

    Summary

    Mercy Hawthorne was born and raised in the Grove, and as wonderful as the Grove is, it's a very small world to confine oneself to. So, it only stands to reason that at seventeen, she'd like to get out and see the world a bit before she takes the Vow of the Eleven and ties herself to a sacred hawthorn tree for the rest of her natural life. Or, at least, that's what Mercy tells her father, anyway.

    To be fair, she was planning on returning after only a summer in Wizarding London, but Tom Riddle, well. He has a way of making her wonder whether maybe her fate lies outside the shade of the Grove after all.

    Summary

    The year, 1999. Harry Potter’s nearly a year into his Auror training, recently engaged, and the proud owner of a little house in Ottery St. Catchpole that’s completely falling apart. Ron and Hermione have been married less than six months, and the Wizarding World is slowly starting to recover from all that they’ve gone through.

    Harry is only just settling into adulthood, and frustrated with the world around him, when Draco Malfoy walks back into his life.

    Why is Harry dreaming about prophecies again? What’s wrong with Muggle London? How wise is it to drink unidentified potions? What happens when you break all the rules?
    All of these questions (and more!) may or may not have answers in this story.

    Summary

    Draco can think of only one way to outclass his pleat-front-khaki-wearing politician ex, and that’s by making headlines with an obvious upgrade. And who better to upstage the cheating bastard than the Saviour of the World, Harry Potter himself? Sure, Potter is a little rough around the edges in ripped jeans, a rumpled tartan shirt, and a permanent scowl. Draco reckons a haircut and a shave wouldn’t hurt, either. But Potter is also in need of a Healer willing to keep his secrets, and Draco is just the man for the job. It’s a perfectly reasonable exchange. They need only attend a couple parties arm-in-arm, smile nicely for the paparazzi, and tolerate each other long enough to convince everyone they’re smitten. In return, Draco will keep Potter alive and in one piece.

    But it isn’t long before Draco realises he might be in over his head, because Potter is ten tonnes of trouble packed into a leather jacket, and seems keen on hurtling himself towards death on the back of a flying motorbike. And that says nothing of Potter’s penchant for fire-breathing beasts and things that bite.

    Ah well, at least they’ll have some fun while it lasts. After all, Draco always did like a bit of danger.

    Summary

    Mid-September, nine Beauxbatons students spontaneously appear in the middle of the Great Hall, amidst blood, smoke, and ritual fire. Upon investigation, the Hogwarts faculty and ministry aurors discover the one who transported the group is Vega Lang, one of the nine. A witch merely fifteen years old. A witch the ICW reported missing the last six years. A witch whose entire family perished in a serial spree of arson, which destroyed many of the most ancient Chinese families, the Langs being the first.

    Death seems to follow the girl, some whisper. Only she and her siblings escaped death during that summer of genocide. Only she had the wherewithal to leave one location with anti-apparation wards, and appear immediately in another such location.

    Who exactly is this girl? Is she a perpetrator or a victim? Prime Minister Hermione Granger refuses to believe Lang’s presence during both tragedies is coincidence, despite what members of the ICW claim. How could no one notice a missing child right under their noses for the last four years, albeit in another continent? Lang’s account is sparse; her extended family's and the ICW's even more so. The minister’s logic, and dare she say, gut, tells her none of it is coincidence.

    Summary

    The first step to becoming an Animagus is to hold a Mandrake leaf in your mouth for a full month. The trouble is, it's very difficult to speak clearly with a leaf adhered to the roof of your mouth (especially when you're trying to hide it from your best friend.)

    Between a drastic change in school policy and the dark lord infiltrating the school, Harry and his friends come to the understanding that nothing will ever be the same again.
