Overshadowed - An HP Marauders Era Story

Disclaimer: I don't own the Harry Potter franchise, but...

Many people have heard of the McKinnon family. Marlene McKinnon was famous in her time at Hogwarts, cousin to the one and only James Potter, and sister to four older brothers. Friend of Lily Evans, Alice Prewett, and Dorcas Meadowes. You've heard of her, yes? Well, she had a sister. A twin, to be exact. Overshadowed by Marlene, Gwen lives her life from behind a camera. Never being mentioned, or considered important. That is, until she is.

Disclaimer: I know that Marlene is actually a half-blood, and only distantly related to James Potter, but in this story she is going to be a pure-blood and James' cousin. Just to get that out of the way.
Also Disclaimer since I've now checked it as finished: I'm not coming back to this story anytime I can think of, but after 6 and a half chapters I just added the plan to the end. I hope you still enjoy :D
