Disclaimer: Seeing as how this is on a FANFICTION website I would think you would know this. But, just in case, everything Harry Potter belongs to J.K. Rowling. I'm simply adding an O.C. or two, and playing with the story.

A/N: Story is canon up until Christmas Eve.

Person Speaking: "what they are saying"

Actual story

Setting up the story:

Harry James Potter, 11, small and skinny for his age, he has unruly black hair, and bright green eyes. His adopted sister, Jasmine Potter, also 11, was small and skinny for her age as well, but she had soft, sun kissed, golden hair, and moonlight struck silver eyes. But, if she wasn't careful they could change to other colors.

For you see, her, and her brother, aren't normal kids. They are actually a witch and wizard. But they don't know that. Not until a half-giant by the name of Rubeus Hagrid knocks down a door and tells them. The next day he takes the two of them too Diagon Alley where they learn more about magic, and receive their wands.

Harry's: Holly and phoenix feather, eleven inches, nice and supple,

while Jasmine's is: Cedar and phoenix feather, thirteen inches, also nice and supple.

On the train ride to school the two get in an argument about virtually nothing, as siblings tend to do, and Jasmine walks off. So, Harry becomes friends with Ron Weasley, while on the other side of the train Jasmine becomes friends with the blond, Draco Malfoy, they had met in Diagon Alley.

At the school they go and sit on a stool to be sorted into one of four houses:

Harry's sorting;

Sorting Hat: "Hmm, Difficult. Very difficult. Plenty of courage, I see. Not a bad mind either. There's talent, Ah my goodness, yes - and a nice thirst to prove yourself, now that's interesting... So where shall I put you?"

Harry gripped the edges of the stool and thought, "Not Slytherin, not Slytherin."

Sorting Hat: "Not Slytherin, eh? Are you sure? You could be great, you know, it's all here in your head, and Slytherin will help you on the way to greatness, no doubt about that - no? Well, if you're sure - better be…

GRYFFINDOR!"

Jasmines sorting:

Sorting Hat: "Hmm, very interesting, are you aware you have occulemecy walls up?"
Star: "no"
Sorting Hat: "well than, your subconsciously protecting something, do not fear child, I won't pry. Where to put you...
You're extremely brave, but also loyal, wise, yet cunning. My dear I've sorted students since the time of the founders and I've never met someone who belongs in all four houses to the extent that you do. Everyone usually has one trait that's stronger but you, your balanced. So, let's see, you're scared, but of what, I can't see, so I think the best, safest place for you, would be...
SLYTHERIN!"

And so starts their adventure.

Harry becomes a part of the Golden Trio with Ron and Hermione while Jasmine becomes part of the Silver Trio, with an Italian boy with black hair and black eyes by the name of Blaise Zabini, and a boy with brown hair and dark blue eyes named Theo Nott.

The difference between the trios is that sometimes the Silver Trio becomes a Quartet, when Draco Malfoy a blond hair, liquid silver eyed boy, hangs out with them.

While Harry deals with three-headed dogs, other students, professors, Quidditch and such, Jasmine is learning the corridors of the school, learning advance spells, making friends in all houses and enjoying life away from her Aunt and Uncle's house.

Everything becomes fairly routine, until Christmas Eve.

When everything changes, or does it?
