by Italo Calvino (1979).
I adore Calvino, ever since I read Invisible Cities in a writing class at Pratt.
This book is wonderful metafiction, writing about reading, ten unfinished novels, and the story of the Reader and the Other Reader, whose lives intersect as they keep chasing down books which have no endings. Calvino is a master--each novel is written in a different style, flawlessly, and at the same time, intertwined with larger hints and reflections of the big picture he's painting. I'll bet it's a favorite among grad students, one of those novels you could analyze and chart endlessly. For my part, I'm happy to note the stylistic sophistications as they pass underneath my eyes, and just keep reading.
