Induction (Severus/Harry)

Induction by Shivani
https://www.fanfiction.net/s/1925071/1/Induction

I will be honest once I realized where the story was going I was not sure about continuing. But I liked the Shivani's other stories so continued and I am so glad I did. The content is disturbing on many levels and reinforces the idea that I will never undergo hypnosis but this is a great story. Severus Snape is complicated and hard to write but the author does a great job and I have to admit the second to last chapter was hard as hell to read but the author pulls it off. Harry has grown into the wizard he always could be with the help of Severus and in the end they realize that together  is where they want and need to be.

Forsaken (Harry/Draco)

Forsaken by Shivani
https://www.fanfiction.net/s/1992755/1/Forsaken

Very good story that shows Harry's Slytherin side. Dumbledore decides he cannot have a gay Golden Hero so to fix the problem he puts a bracelet on Harry that acts as a shock collar. Anytime he has thoughts about another male the bracelet gives more and more pain. When he starts to get shocked for not being happy he decides that since Dumbledore is as bad as Voldemort maybe he should switch sides. He also takes a few others along for the ride. The story moves a little too fast in the beginning but begins to taper down into a good read. The characters reaction to the great revelation about Harry are hilarious especially Hermione's. There are some cliches but overall the story is funny with some drama and an interesting look at Harry and his relationship and influence on others. The author states that they were worried about Voldemort's characterization being to AU but really he has won he can afford to be generous and become more human. After all who is going to stand against him especially now that he has such a powerful heir.

Incorrigible Infatuation (Marcus/Harry)

Yes I know I recommended this earlier but all I did was a blurb and a link and this story deserves so much more. Awesome story with a rare pairing of Marcus and Harry. The way that Marcus is depicted and the reason for the the way he is will surprise you and is well done. The author makes the character believable and sympathetic. He is willing to go against everything he was brought up with to be with Harry and he ends up pulling his friends with him. The confrontation with Voldemort is awesome and he learns that he is not a monster. He is not nice, handsome, or gentle, but he is exactly what Harry needs. I wish the author would expand the Neville connection or do a followup.

Dark Repercussions (Harry/Many)

Dark Repercussions by Jessiikaa15
https://www.fanfiction.net/s/8312363/1/Dark-Repercussions

Great, great story on what happens when Harry is pushed too far.  This is a dark Harry Potter story full of torture, rape, mutilation, angst, drama and surprisingly humor as well. After 5th year the assasain Sang Lys is created and he goes on to collect others for his team. I won't give out names but a few will shock you. The story is well paced and the characterization is interesting. While the characters are very different from canon they are believable and there are no sudden jumps in their development something I detest. You need to go into this story understanding that Harry is fundamentally insane. My only complaint with the story and with all the author's stories is the spelling. While there are some errors due to the fact the author is English most seem to be auto correct giving the wrong word. The author needs a better beta to catch the problems as there is something in every chapter. Other then that which is ignorable the author has done a great job.

Harry Potter and the Descent Into Darkness (Voldemort/Harry)

Harry Potter and Descent into Darkness by Aya Macchiato

Harry Potter and The Breeding Darkness by Danyeallesama
http://hp.adult-fanfiction.org/story.php?no=600095379&chapter=1

Awesome story I do love Harry grows a backbone story and the connection with Riddle is so open to interpretation. In this Harry has no support when his name is pulled and in the process of trying to calm himself he retreats to his mind where he finds that his magic has placed a large barrier against something. Upon pulling down the barricade he realizes that the darkness does not have to be feared. He also finds out that over the years he has been using a lot of magic on a daily basis for the blockade and now that magic is accessible to him. He slowly realizes that he is not a light wizard and the there is more to Moody then he thought. He confronts the deatheator in disguise and asks to be taken to Voldemort. The first story shows Harry's trip to being a dark wizard and his alliance and help in restoring Voldemort. In the second story the relationship between the two really begin as they start to gather allies. Harry's character grows with the story he is strong, mature and ready to seek revenge on those that betrayed him and stand at the side of the only one who can match him. The story is by two different authors but definitely worth the read.

Matyrdom and Paradox (Harry/L)

Martyrdom and Paradox by UchidaKarasu
https://www.fanfiction.net/s/5730598/1/Martyrdom-and-Paradox

Great crossover story between Harry Potter and Death Note. Harry is in the wrong place at the right time to run into L while in Japan. He becomes fascinated by the detective to the point where he decides to help him against Light and the shinigami. It turns out that as the Master of Death he is immune to the power of the Deathnote and the shinigami are aware of him. He eventually tells L the truth about the wizarding world and the relationship deepens. Harry is determined to prevent Light from killing L and ropes in Hermione to help.

The Rise of the Drackens (Harry/Blaise/Draco/OC/OC)

The Rise of the Drackens by Starlight_Massacre
http://archiveofourown.org/works/384548/chapters/629550

Excellent story, I have to admit I love creature Harry and this one is a beauty. I have read a couple of other dracken stories one I could not get past the first chapter and the other I read some but I did not like the characterization and it just did not keep my attention. This one starts out like most stories where Harry wakes up with a surprise but then it begins to get interesting. Once he realizes what is happening the Potter luck kicks in. There is drama, death, misunderstanding, prejudice and that only in the first few chapters. It is an amazing story with a realistic look at teenage pregnancies, making compromises in relationships, how friendships can break and new ones can be born. Getting pregnant is easy, raising babies is not even when your a powerful wizard with four mates. Watch has Harry takes on the challenge of mates of different ages, children lots of children, in-laws you love and mother-in-laws from hell, learning to trust others and most of all learning that it is okay to be happy. Oh and lets not forget the hot sex scenes and I do mean hot.

Skin Deep (William/Harry)

Skin Deep by Vingilot
http://www.fanfiction.net/s/2519543/1/Skin-Deep

Awesome story but warning this is a story that deals with rape and the aftereffects. Harry has been broken and held together through sheer determination and the love and support of only a few people. When Dumbledore finally reveals to Snape that Harry is his son he also reveals the depths of his knowledge of Harry's pain. Snape will do anything and everything even put up with Weasleys in his home to protect and avenge his son. Dumbledore will pay. This is one of the first slash stories I read and hooked me on the genre since. I do not think I have seen tattoos used in the manner before and love the reactions of Hermione and Ron. Here they really are the Golden Trio.

Unlikely Heroes (WIP)

Unlikely Heroes by KusanoSakura
http://www.fanfiction.net/s/7598990/1/Unlikely-Heroes

This is an awesome fic that is already at 61 chapters and 253,492 words and still going. It has it all magical creature inheritance, soulbonds, evil Dumbledore, stupid Ron and hot couples. I admit I have a problem with Harry being too wimpy in the overkill abuse fics. But this author has managed to make a likable character but the interaction between Lucius and Severus pretty much steals the show then you add Remus in. The hotter parts of the story are on Adult Fanfiction to avoid the story being shut down.

Dabbling with the dark (Voldemort/Harry)

This is one of the more interesting Harry ends up with Voldemort because he does not immediately fall in love and jump in bed with him. There are plot twists so that you are at times not sure of his loyalty and the ending and interpretation of the prophecy is good. Harry is strong, dark and most of all intelligent. Voldemort is sneaky, evil and so deliciously dark and sexy that you can see why they work so well together. I love Auntie Bella.

Her other stories are just as good.

Incorrigible Infatuation (Marcus/Harry0

Call me strange but I love this pairing unfortunately there are not a lot of stories but there are a few good ones. this was the first one I read and I love it.

Harveste Addams (Slash)

I love, love, love this series and cannot wait for the updates. Kyaru-chan is a wonderful, sarcastic, funny, evil writer. As you can tell this is a cross-over with the Addams Family. I have read several but this has to be my overall favorite. I still do not who/how many Harry will pair with but it should be interesting.

a few qoutes:

Pugsley, this is your new brother. He's just killed his family."
"Really? I'm so jealous!

A ghastly face appeared on the surface of the potion, the stuff of nightmares, looking like it had been dredged from the depths of hell.
"Grandmama, how lovely to see you."

"Of course not. I shall tell her about the Howler. She'll have such fun with it. I wonder how many screams it can hold?" (Harry talking about Wednesday)

Actually you would like anything by this author http://www.fanfiction.net/u/546831/kyaru-chan

Sneaking Around Konoha (Kakashi/Harry)

I do tend to love Naruto/Harry Potter crossovers. This is a Kakashi/Harry that is light hearted and fun to read. I can so see the two of them together. In this one Harry and Teddy are stranded in the Naruto world due to a spell and after wandering and of course saving people settle down in Konoha so Teddy can be come a Shinobi. His Jounin is Kakashi.

Redemption (Harry/Licker) (Warning)

This is not my usual style of story it is a cross between Harry Potter and Resident Evil, it is dark, there is beast rape, there is insanity. Yet for all that it is an intense, believable story that grabs you and does not let you go. You can see why he does what he does and realize this is a man that has gone through insane and out the other end to a semblance of sanity. There is always a price to pay for immortality. In a twisted way Harry gets what he wants and magic gets a chance to redesign the world.

Life Renovations (Draco/Harry)

This is a multi-story that begins with Harry in a coma with the delicious Draco playing the white knight. I do love Draco/Harry stories when they are done well because there is just so much potential. This has the manipulative, evil Dumbledore that for once is not over the top and a strong Hermione that lives up to her potential with the creature inheritance and the excellent, well crafted OC's this is a great series.

The Black Bunny (Voldemort/Harry)

This is one of those fics not to read at work because parts are funny and your co-workers will look at you funny when you are laughing at your computer. This is one of the more realistic Voldemort/Harry and Hermione not only supports him but is an essential part of the story.

Harry wants out, he decides to live his own life and screw both sides but of course the light cannot lose their weapon.
