Just finished listening to the "Omnivore's dilemma".
I liked it a lot. As a vegetarian, I tend to stick to my own bubble. I have to admit that this book seemed to be written in a quite objective way and it exposed me to points of view which were different from mine and which I do not think about too much in my daily life. I count it as a very good experience.
Would recommend it but NOT on audible - the narration was overly dramatic for my taste.
