I borrowed this book because I needed it for a class at short notice. Many thanks to the authors for having the foresight to make this an audiobook. It was a pleasant surprise. The disappointment crept in when I had a hard time following. This text, in print, has writing prompts which do not translate well in the audio version. A companion PDF of the text would have been awesome. Until then, potential customers should download this audio FILE, which currently has no text companion, their own risks.
