Padgett Powell will read from and sign copies of his recent book, The Interrogative Mood: A Novel?  A work of fiction entirely in questions?  Could it be?  Is it possible?   This is the kind of book that makes you want to read passages aloud and leaves you looking at the world with fresh eyes.  Powell, the author of Edisto, teaches in the Writing Program at the University of Florida and writes for The New Yorker, The Paris Review, Harper’s, and other publications.
