If you write for the young adult market, and if you're unpublished, here's a contest you may wish to enter. It's the Delacorte Press Contest for a First Young Adult Novel. I'm not certain how they're affiliated, but Random House is involved somehow in the mix.
I'm providing a LINK HERE to give you the details. You will have to submit your contest entry by snail mail, along with a SASE. (Remember the old days when we did it that way for every submission? If you're not old enough to remember that, we don't want to hear it.)
I will mention there's a $1,500 cash prize and a $7,500 advance against royalties. There is a maximum of two entries allowed. And, you only have until the end of the year to submit. You entry must be postmarked by December 31, 2010 to be eligible.
