My all time favorite audiobooks would be by Dean Koontz "Fear Nothing" and "Seize the Night". I haven't read the actual books yet, but I do have them. I have listened to the audiobooks a couple times. Love em.
But I like Iris Johansen, and Jonathon Kellerman,and Sandra Brown, I am really not picky, as long as its good! I am not much of a Grisham fan, mostly have listened to his books and not read them, but am reading "The Summons" right now, and can't get enough of it!! Can hardly put it down!! I just read "Paradise County" by I think Karen Robards, and I really couldn't put that one down!!!
