Percy Jackson and Mortal Instruments Crossover

Okay, I know that this is a crappy title, I'll come up with a different one soon. If any of ya'll want to be in the story just comment your appearance, personality, if your a demigod (if so who's your godly parent) or a shadowhunter, and whatever name you choose. You can also PM me if you want. I'll try to update often, but some updates might take a while because I have a lot of work to do for school. Hope ya'll like the story. Please comment and vote. Just not to mean of comments if you don't like the story.
I DON'T OWN ANY CHARACTERS BESIDES MY OWN WHICH WILL BE SAVANNAH SILVERSCAR.
