48 parts Ongoing Sirius Black/OC!
Rose Evans was a perfectly abnormal girl, thank you very much. A freak, a prankster, a twin, David Bowie's greatest fan. And, on the summer of her eleventh year, she received a letter unlike any other. She was a witch. Oh, but she was so much more than that. Join her on her mad, balmy, absolutely crackers life as the fifth Marauder - Remus Lupin's best friend, and a girl unlike any other.
There will be heartbreak, torment, grief, and shameless Slytherin bashing, but there will also be mischief, joy, Marauder antics, Christmas fluff, and magic. This is the life story, more or less, of Rose Marianne Evans and the Marauders. Come and join the fun.
