Listened to the audiobook version.
The book itself: do not listen or read it on a full stomach. Do not listen or read it when you are about to eat. Just... do not. There were times when some of the details had me staring in horror at my audio device. A few times I felt my stomach turn. It is like a train wreck that you can't stop watching, you just plow onward through the chapters because each chapter is more horrifyingly interesting than the last. Part of this mind boggling need to press on is probably due in part to the author's wry comments that make the book more, dare I say, palatable. There is a strong moral bent towards body/organ donation, but otherwise it is pretty fair in leveling cultural perceptions from both sides of the field on various touchy subjects related to (the use of) dead bodies.
The audiobook: narration was excellent. I think Shelly Frasier was the narrator of my copy and her voice was very soothing but wondrously inflective* on those small bits of humor I mentioned above that really helps drag you through this crazy book. I think I would listen to just about anything she read regardless of topic.
*Shut up, spellcheck. I can make "inflective" a word! English language +1.
