Audiobook version. I chose this book based on recommendations I read on Good Reads. The premise sounded intersting, and I think the story has promise. I might even try again sometime with the print version. The audio version was so badly performed that I gave up after about half an hour. Perhaps the reader was attempting to emulate the bleating of sheep or something. I'm not sure, only that I was sorry I wasted one of my Audible credits on it.
