"The genesis of the library was very simple," says Stahl. "I happened to read Nabokov's The Real Life of Sebastian Knight and Graham Greene's The End of the Affair in quick succession, and was struck by the number of nonexistent novels mentioned, and at times even described in each book."
Since I've been going through Nabokov's works recently I'm going to use this as the deciding factor for his next book to put to the top of the TBR pile.
