Chatter rolls with Claude, David, Torie, and COB fave Louis Bayard.  They cover dance clubs, Pale Blue Eye(s) and Commaders fans. They marvel at Iowa City, home to everyone who’s writing a book.  Literary legend (and Lou’s pal) Thomas Mallon zooms in to share two books from his exceptional and large collection of work — “A Book of One’s Own” and “The Very Heart of It.”  The first captures the hearts and souls of diverse people and places in time.   “The Very Heart of It” vividly portrays the terror of the AIDS epidemic and the vibrant cultural scene of 1980s New York.  Mallon’s a legend and a true writer’s writer.
