There's a photo essay in Publishers Weekly by David Levithan that covers some highlights of the festival (which will happen again next year in March, so you should come!). Here's a shot I love from the panel about how putting your characters in a new setting can reveal things about them.
(L to R: Jennifer E. Smith, me, Bennett Madison, Gayle Forman and Kristen-Paige Madonia -- really fun company.)
Happy Friday!
