Crossover: Harry Potter crack ficlets, aka the author didn't bother to put a title, by Asuka Kureru. A series of ficlets about a year spent at Hogwarts by Team 7. As titled, the ficlets are crack. Little pieces about Naruto using the Sexy no Jutsu to mess with Malfoy, Kakashi's conflation of interhouse cooperation with teams, etc. Too bad there's not more of them. One of the few ninja-at-Hogwarts fics I can stand. I don't mind magic-in-Konoha fics, but something about ninja-in-Hogwarts just rubs me the wrong way.
Running Home, by kirallie. WIP. When Death Eaters attack Privet Drive, Harry flees the country, fearing that he'll be blamed. He ends up in a cell in Sound with Kakashi. They escape and make their way to Konoha, where Harry seeks out Iruka, who is a long lost relative. On the way there, they're attacked by a snake, who ends up as Harry's. Harry's adjusting and not planning on ever going back to England. Then Kakashi gets sent on a mission against wizards and Harry must go back to rescue him. They recover Kakashi and return to Konoha, but the problems aren't over yet, as Voldemort wipes out Hogwarts. Harry wipes out Voldemort, Naruto returns, Harry's unofficially assigned to a team and yes, it's a WIP, but anyone else would have put a 'The End' sticker on it already and called it good. I like the Kakashi/Iruka interaction in this one. In fact, I mostly like this story for the Kakashi bits.
Harry Potter: A White Coat for My Blond, by Scyllablue. Harry/Lucius. After the war, the remaining Death Eaters are arrested, including Lucius Malfoy. He expects to receive the kiss, but is instead handed over to Harry Potter. Harry knows that Lucius is a veela, that Voldemort used this fact to enslave him, and has married Lucius to get him free of Azkaban. Harry is also a Veela and woos Lucius while showing him how to be a Veela. The one where Lucius ends up doing Harry's correspondence 'cause Harry really sucks at it. Sexiness abounds, although the issue of Lucius being evil is hand-waved over by saying everything he did was 'cause Voldemort had his Veela coat. The story doesn't have a good explanation for how Lucius was seemingly so strong-willed and in control of himself while being a whipping boy; however, it's still a pretty story. (Ooh, shiny!)
Harry Potter and the Methods of Rationality, by Less Wrong. WIP, but too good to care about that technicality. Well, if you like crack, that is. What if Petunia hadn't settled for Vernon Dursley and ended up with a professor of biochemistry instead? What changes would there be in Harry? Well, basically he's a nutcase. Some similiarites personality-wise with Tipsy Time Travel Tale, linked below. I'm rather fond of the scene where he shops for school supplies with McGonagall and drives her crazy using logic as his weapon. And subverts Draco by pretending to respect him, thus causing Draco to do the same thing back to Harry as Lucius walks in. Lucius is, naturally, horrified. As Harry puts it, "He was in a situational context where those actions made internal sense -". Has other tremendously fun gems like, "If I lied the first time, I'm not going to tell you the truth just because you ask twice." Then things get serious and Quirrell (the first useful cunning Quirrell I've ever seen) teaches Harry the important art of losing. Quite the epic tale.
Let The Guilty Pay, by Janara. Harry's fed up with being Harry and engineers a potion mishap that turns him into a girl. With the change of gender, he lets go of the Harry Potter persona and embraces who he really is, to the happiness of nobody. For McGonagall, it's the last straw and she browbeats Harry, who resorts himself into Slytherin. Unfortunately, Ron now hates him and severs all relations between the Potters and the Weasley. And also Umbridge is still on the prowl, assigning detentions with blood quills. Harry calls down magic to take revenge on her -- and inadvertantly gets a whole lot more as he's been a lot more wrong done by than he knew. He's actually Draco's twin brother (both bonded to a pair of elemental cats) and Snape's destined mate. The story ends with magic's revenge -- no actual romance in this one.
Matrimony, by Ladyofthemasque. Hermione/Snape. School's nearly out and Hermione's an orphan. Her evil aunt is spending her inheritance and her only recourse is to get married immediately. Unfortunately, the Wizarding world requires that a marriage be shown to be compatible in order to be valid, so she can't use either Ron or Harry. Her matchmaking service finds someone who's 98% compatible and ready to marry immediately. Hermione jumps at it -- even when it turns out to be Snape. Some moments of extreme hilarity, a sexy wedding... er, evening, and a smart fic all around.
Potion Commotion, by mahaliem. Harry/Snape, Lucius/Neville. Post Hogwarts fic. Snape makes a potion to cause fear of himself in Harry. Albus tampers. Snape gives Harry the potion at the Fourth Annual We Killed Voldemort party. Unfortunately for him, Harry is fleeing Lucius at the time and so decides to pretend that he's madly in love with Snape. Snape decides that he must have messed up the potion and starts treating Harry with antidotes. Meanwhile, Lucius is stalking Harry at the latter's clothing shop and Harry, having discovered that Snape treated him with a potion, is pursuing Snape. To get of Lucius, Harry fobs him off on Neville. Neville gets the measure of Lucius and Harry gets Snape. A very merry romp. With sex.
The Abundance of Her Charms, by Odogoddess. Snape/Luna. After his death, Hogwarts doesn't want Snape's portrait on the wall, even though he's a past Headmaster. Luna finds a way around that by locating a wall that's been spell damaged and which Hogwarts cannot affect. However, while he is now hung in Hogwarts, as the castle can't affect him, he also can't affect the castle -- no going wandering into other paintings and the like. Snape is not particularly happy about things. Harry commissioned a lavish painting for him with everything he could possibly want, but the part of Snape that lives on in the portrait would just as soon not be living at all. However, that isn't a choice. Luna continues to wander in and out of his life, talking to him, and eventually finding a way for them to exchange letters. They do so for years, long after Luna's graduated and gone off adventuring around the world looking for fantastic beasts and so on. Their relationship flourishes. Luna comes back to Hogwarts; they have the portrait equivalent of phone sex. Then one day Luna doesn't return to her quarters. With Luna dead, Snape retreats into a kind of catatonia -- until there's a knock on his door. Luna's had her own portrait done and they're together forever and ever. Or until the charms fade. Long summary. I like best their developing relationship and Snape's mood -- how his portrait self can't be happy even with all the supplies he'll ever need and all the solitude he's ever wished for.
The Heir of Magic, by DisobedienceWriter. The story starts with Draco, but basically it's about Harry and how he's becoming something more than himself. Harry's in touch with magic more than other people. He asks it to do things and it does things that other people think impossible. Harry knows he's losing his sanity as he becomes, and is working on solving two problems: saving the world from Voldemort, then saving the world from Harry Potter. It gets a bit weird toward the end, where Harry destroys the British government and forces them to start over from scratch, but otherwise an interesting take on the relation between sanity and power.
Tipsy Time Travel Tale, by Yunaine. Unfinished WIP, but what's there is so hysterical and original that it's more than worth reccing. Harry gets dragged back in time because an anonymous being of power found his life to be excessively boring and wants him to do it over again -- but fun this time, so that the being can get some entertainment value out of it. Harry is not pleased with this and decides to take his pique out on the world. Starting with, natch, the Dursleys. Fun with wandless magic! It goes on from there and it's not nearly long enough, but I love a good laugh.
Uncomfortably familiar, by BrennKinn. WIP. Albus gives Harry a book on how to become an Animagus, hoping the transformation will help heal Harry of the events of his fifth year. Unfortunately, Harry transforms into a black phoenix. In this story, the shape is linked to a certain mindset and the phoenix transformation is linked to abuse. Harry's particular version of it speaks of long term abuse and no one that become a black phoenix has ever transformed back. Seems like Dumbledore's screwed. So he sends Harry with Snape, not realizing that Draco will come across the text and make the conclusion that he wants to be a phoenix and prefers that to being human. Unfinished, but this is my absolute favorite Harry-is-a-phoenix-animagus fic and I reread it ever so often.
Unwanted, by Sly Stir. Snape/Harry. Harry lives two lives -- one as The Boy Who Lived and one as the Dursley's obedient slave cum whipping boy. Until people finally twig to the fact that he's being mistreated. Snape goes to fetch him and they discover that Harry's a Shefro, an empathic hemaphrodite with wings. The Dursleys have simply been cutting the wings off every time they grow. (There's also a moving scene where Harry goes out in the rain and cold to have them at the Weasleys, directing Ron via note to put him in the garage until he's recovered.) The empathy makes Harry a victim of other's emotions, which is why he's been the perfect slaveboy. Harry and Snape then fall in love, which is where I check out of this fic. Harry is simply written too vulnerable, too young, for me to buy (or even want) the romance. Unfortunately, the scenes with the wings stick in my head and make this story quite unforgettable.
What Men Call Love, by lordhellebore. Snape/Luna. While Snape lived through Nagini's attack, he's still suffering from it nine years after the war's ended. He's gone through any number of attempted cures, some more absurd than others, when he's persuaded to give Luna a try. Luna does heal him, using crystal magic, and basic human empathy. They quietly fall in love and court. It's hesitant and cautious -- and infinitely sweet -- and then Luna decides to give things a push. Absurdly lovely hurt/comfort.
