A/N: Hey all. This is my first fan fiction. I know, super cliché plot. Just bear with me! Hopefully my OC is not a Mary Sue. I hate this prologue, but my little brother is encouraging me to upload it anyway. Anywho, please read and review and I will give you a virtual taco! XD

Prologue

Secrets. I've never been fond of them, yet I've kept secrets for months on end with no one the wiser. I suppose I have some sort of weird talent. To keep up a mask, a façade of lies for that long requires a lot of natural-born skill. I don't mean to brag, but I've always been clever.

I figured it out when I was ten. It wasn't that hard to see. My birthday was the same as his, and I had the same odd scar- although mine held the shape of a crescent moon. I don't suppose you know what I'm talking about. Well, maybe if I were direct it would simplify everything.

My name is Megan Harlnott, and I am the twin sister of one Harry Potter.

Surprised? You should be. Only seven are privy to this secret. One, of course, is me, though I wasn't supposed to know until Dumbledore told me (thus his surprise when I told him I already knew). The second is Dumbledore himself, and he also informed my adoptive parents in a letter when he so graciously bestowed me upon them (coughdumpedmeontheirdoorstepcough). The fifth is an Unspeakable by the name of Marlee Jones, down at the Department of Mysteries. Merlin knows how she got dragged into this. The sixth is my pet snake, Ophion, in who I confide everything. Yes, I am a parselmouth. Don't be hatin' on the snakes. Hem. Sorry. That sounded horribly wannabe-gangsta. Anyway....

The seventh and final person to know my secret is- ...you, dear reader.

You thought I was going to say Harry. No. He has no clue. For all he knows, I'm just that weird girl who always seems to be right around the corner. Yes, I stalk him. Not like that you gutterheads! It's completely platonic. I don't really sponsor incest, or twincest for that matter.

It's my job to stalk Harry. I wasn't too happy about it at first, but I got good at it. You'll see.

So those are the seven people (or snakes in some cases) that are aware that there was a second Potter child. Everyone else, from James and Lily's closest friends to their co-workers, has had their memories modified. Dumbledore said that it took him a month to pull it off. And I must say I am impressed. It was probably the greatest feat of mass-obliviation in the history of magic-kind.

You're probably lost. Why would Dumbledore go to such lengths to make sure no one remembered me? I'll tell you. I'll tell you the story of my first year, of awkward relationships and alchemical stones. I'll tell you everything while it's still fresh in my mind. After all, it's summer break, only a few weeks after the fact, and there's no Harry to spy on, so I have plenty of time on my hands.
