1/ 7 Powers by Hamilton Helmer - one investor called this "the best business book in history." Not as well known as others, but based on decades of case studies: the seven strategies that provide extended, sustainable competitive advantage. This book is so important that i may or may not have just published a mystery novel about it...

4/ Zero to One by Peter Thiel: The must-read for any beginning startup entrepreneur.
5/ Never Split the Difference by chris Voss: Specific to negotiation strategy; written by former chief CIA hostage negotiator with surprisingly actionable and often counter-intuitive strategies for 1:1 situations in the business world.
