Elana Johnson at http://www.elanajohnson.blogspot.com/ is holding a query critique contest. If you enter and your name is drawn, will win a critique of your query from someone who reads multitudes of the things; someone who knows what does and doesn't work.
Yes, that's right--you could have your query critiqued by one of these top five literary agents!
1. Kate Testerman-Shafer of KT Literary (critique will be posted on her blog, Ask Daphne)
2. Michelle Andelman of Lynn C. Franklin Associates
3. Mary Kole of Andrea Brown Literary Agency
4. Michelle Wolfson of Wolfson Literary Agency
5. Joanna Volpe of Nancy Coffey Literary & Media Representation
If you're interested (and if you're anywhere near drafting a query you will be,) stop by her blog and sign up. I did.
