I saw yesterday that Roseanna White of WhiteFire Publishing has a great offer going. You can send her a 50 word description of your story, focusing on your main character, and not only will you receive feedback but Roseanna’s favorite 3 will be invited to submit a book proposal to WhiteFire.
You’ll find details over at Shellie Neumeier’s NextGen site. Get to writing!
