Edwin Stern spent twenty years and over 2,000 negotiations learning one thing: deals aren't won with arguments — they're won with reads. As a corporate attorney and high-stakes dealmaker, he has represented everyone from quietly wealthy founders to ultra-high-net-worth families in transactions most people never hear about. His clients don't come to him for legal boilerplate. They come because he sees what the other side is hiding — and knows exactly what to do with it. The Negotiation Black Book is the playbook he never intended to publish. Then he realized keeping it private was a waste.
