I know this is last-minute but there is a contest going on through Writer’s Digest called the Dear Lucky Agent Contest. This year the category is young adult fiction or science fiction. So if you have a book already and want the chance to be published, just click on this link: http://tinyurl.com/a8msdw2 and read the guidelines.
The contest ends January 31, 2013, but is free to enter and you can enter multiple times.
Good luck everyone!
