Who’s your favorite author? Jim C Hines? Tobias Buckell? John Scalzi? (they will all be at ConFusion) Gene Wolfe? Harlan Ellison? Jack Vance?
What have you learned from them? Have you had any contact with them? What questions would you ask?
Can I humbly suggest that you will learn more from them by reading their stories, figuring out what you liked about them and how they pulled it off, than much of what they could tell you?
All of their secrets are right there on the page. There is no hidden code when it comes to paperbacks. This will also prepare you to ask them more focused questions if you do catch their attention.
That way you don’t ask them where they get their ideas.
Just a thought.
