When and Where will The Auditions be held for Percy Jackson and the olympians: The Titan's Curse be held?

I want to audition for the roll of Nico Di Angelo. I'm about 5'7. I wear gles but I can see with out them. I have brown hair and eyes. I'm 13. I weigh 152 pounds bu I'm on a diet. I live in Dallas Texas and I've read all the books and I know they'll have to cast someone for Nico and I really wanted to audition for him. Does anyone know when and where they'll be held? No rude comments please. Thanks.
