Okay so this is just an idea I had. It's written in first person, by Samantha Weasley, twin sister to Ron.
When Milly starts at Hogwarts, she becomes firm friends with Fred and George Weasley. Together with their friends Angelina, Jessica and Lee, they muddle their way through their first year; making friends...and enemies. But you never know what could be lurking around the corner...
When "Louise" is kidnapped from the muggle orphanage where she lives and is taken to Malfoy Manor by a death eater called Bellatrix Lestrange who claims to be her mother, little does she know just how much her life is about to change...
Eleniel Elwing is a pure-blooded Gryffindor. She is starting Hogwarts at the same time as the 4 Marauders. Soon, the five of them become close friends, but Eleniel is hiding something, and the marauders won't rest until they know what her secret is...
Ginny is writing letters to her brother Fred, who was killed in the Battle of Hogwarts. See how Freddie's death affected the Weasley family through the eyes of the youngest, and only female, Weasley.
This is a oneshot I came up with based on some of the characters from my fanfic "Curiosity Killed the Cat". Sirius, James, Remus, Lily and Eleniel are sent 15 years into the future when Remus's time-turner explodes. They find themselves in the dorm of a very baffled Harry Potter...
