Adventures in Scifi Publishing captured and posted a podcast of the panel at Chicago Worldcon 2012.
Vivid Character Building
How do you create vivid characters who pop off the page? How do you avoid archetypes/stereotypes and predictability? Join a panel of writers discussing their techniques and tricks and ask questions of your own.
Carol Berg, Teresa Frohock, Randy Henderson, Kay Kenyon, Bryan Thomas Schmidt
Listening to it, you can tell I was running on caffeine and more caffeine by this point in the con, but all the panelists were great, and there’s some useful tips and info on creating characters.
