a lot more than i expected
The book is very easy to read and understand even for a non english speaking reader.
Definitions and information on every aspect of the subject. It is I think what the title says. after completing the 4-5 first chapters one will definetly see negotiations differently and will be able to analyze situations (see the angles) a lot easier.
Simple terms, readable text, interesting subject, it can be usefull to everyone, since we are all involved in negotiations.
