I originally read this book in Thai Vegan Kitchen in Helsinki. It's ostensibly about communicating with carnists about veganism, but in reality I'd say it's a book about using direct non-violent communication in personal relations. You can find the same concepts in any book about attachment theory, but Melanie Joy presents it all in a more personal way. Useful also if you often find you have trouble communicating the importance of a belief of yours, for example (in my case) free software or privacy.
