Summary: There's lots of girl!Harry stories ... hardly any female!Severus ones. So write a female!Severus story. Her personality still has to be recognisable, but with realistic differences.
The name Severa is not compulsory, give her whatever first name you want. No slash. Preferably Remus/Sev but not required. Harry could be female also but would prefer him still a boy. No Dumbledore bashing.
Summary: On Dumbledore's orders, Severus Snape is sent to Little Whinging for damage control when a young Harry Potter finds himself on top of the school roof. Not only has he apparated there in front of most the school and cannot get down, but the ministry has caught wind of his display and has sent their own representative to investigate with authorization to take control of the boy should it be needed. Who? None other than Dolores Umbridge. Severus has his work cut out for him.
Summary: Harry is in the light side. So is Snape, but Harry is not left unscathed from all of his encounters with the dark Lord. Write a story in which Snape saves Harry from voldemort in a way ( could be kidnapping or a vision) is found out in the process but escapes.
Harry and Snape are forced in hiding by Dumbledore who essigned Snape to tend to Harry's ( any mental illnesses,preferably schizophrenia ) and eventually form a parent and child bond with him. Absolutely no bashing, and no dark Harry or manipulative Dumbledore.
Long chapters and please not be abounded by the author or on hiatus for a long period of time. Abusive Durselys are allowed.
Summary: Not actually a crossover, but a Harry Potter version of Once Upon a Time, with all the HP characters together in a Muggle town with no magic and no memories of who they are, until the curse is broken. Just the show concept really, no need to try and mirror the show's plotlines.
Summary: Adapt Ayreon's rock/metal opera, "Into the Electric Castle" for the Harry Potter universe. Including the narrator and Death, there are 10 characters.
Does not need to be epilogue compliant. In fact, it might be best if you choose to bring back dead characters.
Summary: Girl!Harry story, containing a scene in which a very protective Severus is meeting her (potential) boyfriend. Could be father, godfather or stepfather fic, or he could be just a really protective teacher. Bonus points for creative "If you hurt her ..." threats.
Summary: Petunia never got over her wish to be a witch. When the first Hogwarts letter arrives for Harry, Petunia knows what it is. She devises a plan to send Dudley instead of Harry as the boy who lived. She colors his hair and puts him on a diet (a little!) and presents him to Hagrid when he arrives to take the boy shopping. Finally she has her chance to bask in the fame she believes she deserves. What will happen when Dudley arrives at Hogwarts? Will anyone suspect that something is wrong? And just what will the Dursleys do (nothing too extreme please) with the real Harry?
Summary: The Dursleys never abused Harry. Instead, they treated him exactly like Dudley, and as a result, Harry is exactly what Snape always thought he was. Spoiled, a bully, and thinks himself high above others. When he comes to Hogwarts, acting exactly, if not more, like a James Potter reincarnated, how does Snape and everyone react?
Summary: Harry and Severus are stranded somewhere (doesn't have to be an island, as long as it's remote/isolated with little to no chance of escape) and have to co-operate to survive.
Summary: Sirius is killed after being kissed by the dementors third year. Harry has lost all hope of a caring adult in his life and his behavior spins out of control. Could be drugs, alcohol, shoplifting, disturbance of the peace etc.
