Query: A light in the darkness

You can tell that Roy Williams has served time in the real life trenches of the ad game. There are nuggets of gold nestled within the stories he shares in this book.This is not a "step by step" color by numbers kind of book. It's one that shares the lessons learned by the telling of parables. If you have a solid background in marketing and advertising, then this is great read. If you're looking for a marketing primer, then this is not the book for you.
