[.ca] Negotiation Analysis: The Science and Art of ... (ISBN 0674024141)

Remarkable book for negotiators:
This book has a real wow factor. I was amazed at how much ground it covers - game theory, pscyhology, decision analysis, negotiation stuff. There's a great balance of technical help with easy-to-read conversations between hypothetical negotiators making the tricky concepts easier to understand. You probably won't want to read it from cover-to-cover but every chapter has really useful insights on how to negotiate better with positive or negative counterparts.
