All Emilia knows about Hogwarts is things her brother told her, so when she meets Fred and George Weasley (who somehow already know the castle inside out), how much more mischief will she start creating? Set in F G's year.
Obviously follows Scarlett Potter and the Philosophers Stone. Harry and Scarlett's second year at Hogwarts is predestined to be just as mad as the first, with them getting into just as much trouble for the simple matter of wrong timing (and maybe their own stupid mistakes), and the trouble is only increased for Scarlett due to knowing Fred and George Weasley.
Turns out I'm not inventive enough to come up with a different title. Harry Potter and his twin sister, Scarlett (how cliche of me), are going to Hogwarts - where chaos ensues, and Scarletts becoming friends with a pair of redheaded twins does not help the situation at all.
After the death of his twin brother, George is completely distraught and has no idea what to do with himself, but will his best friend be able to help in through it or will her arrival just make him even worse? George x OC, slightly OOC in my opinion, at least. Oh, and the summary is really rather bad, so please at least attempt to read my awful writing :3
