I recently discovered audiobooks - I know, not exactly new but better late then never... so far, I have "read" Kitty Kelly's Jackie Oh! (a guilty pleasure : )
and which I think actually sounds better then it reads.
The one I really recommend, read by the author himself, is Frank Langella's wonderful memoir, Dropped Names: Famous Men and Women As I knew Them. Of course, my favorite chapters are on the ones about his friendship with the Mellon family but it is really all really good.
love, kisses and happy listening, Juliana
