Q: I heard about your blog at a writer's conference this weekend. I'd like to send you a query but I absolutely do not want it posted. Can you guarantee that?
A: This blog does not post queries that come to my agency. Ever.
This blog posts queries from writers who address them specifically to Query Shark and are asking for the query letter to be critiqued.
Two entirely separate things. Queries to the agency are not fodder for this blog unless they are resubmitted by the writer and addressed specifically to the Shark.
