VP is looking for short stories, essays, poems, even comics. The editors' tastes are diverse and the pieces they print will have two things in common: they are astonishing in some way and they appeal to a teen audience. Think you've got something that would be a good fit? Visit the VP submissions guidelines for more information on how to submit.
So go dig through those files, look in the bottom desk drawer, search around in all those places where you store your best teen lit stories/poems/essays. You know, the ones that you couldn't find a home for because that home didn't exist. Now it does.
And don't forget to spread the word!
