is she a riddle? Please continue!

It would help your fic if you actually knew something about Egypt. Modern Egypt, not pharaonic Egypt, which you seem to think Egypt still is. No one in Egypt wears lotuses in their hair, for God's sake. Destiny is NOT an Arabic name (Egyptians do speak Arabic, btw). I'd say Destiny is more of a Mary Sue name. Nor do Egyptians have "piercing blue eyes." Nor are Egyptians pale; they generally have dark hair, dark eyes, and very tan skin.
Aside from all of that, your character is a blatant Mary Sue. Mysterious transfer student? Check. Exotic background? Check. Gorgeous physical appearance? Check. A "dark secret within her soul"? Check. Cheesy, melodramatic name? Check. You really should work on making a character who is actually a human being, rather than a cardboard cutout of perfection.
Moreover, it's pretty obvious that her secret is some kind of deadly illness that will slowly kill her (but never make her ugly; she will waste away while continuing to be ethereally beautiful) while the rest of the characters mourn.
Sorry if this comes across as a flame, but since I'm half Egyptian, it irritates me when people cobble together cliches about ancient Egypt to make their fic seem more "exotic." Also, I would recommend a beta reader and proofreading, since you have a bunch of fragments and grammatical errors.

oh... I wonder if she eats frogs? XD

I like the sound of where this is going.Write more soon!Who's point of view is this written from?

Good story so far but who's point of view is it from? Can't wait for the next chapter. :-)

keep writing! your stories are really good but you NEVER finish them! Plz finish 'em!

Please finish it. Aren't you going to? It's very good, but you don't seem to finish any of your stories...

Loctus? Surely you mean the rare and lovely lotus flower, yes? L-O-T-U-S?

H'm. Well- can she play Quidditch? If she can, she's all right with me. I'd like to know who she's mourning. I think Egyptians speak Arabic. Good start. Waiting for more.
