Query: What tommorow's creative stars are reading tonight.

Luke Sullivan is one of those rare people in advertising who when you ask them, "Gee, how do you come up with those ideas?", he actually has an answer. I've admired Luke's work for years. He's a brilliant creative mind. Obviously, he's equally talented as a mentor for anyone who wants to know how it's done. Highly recommended.
