"Marketing" is a broad term; it's like saying 'what's a good book on software engineering?' What are you wanting to learn about marketing? There are interesting books that give you lots of tactics for early-stage startups (Traction by Gabriel Weinberg, for example); books that tell how to think about Brand Strategy (for example, Building a Story Brand by Donald Miller); books that delve into psychology (Influence by Robert Cialdini); and many other things. Marketing encompasses high-level strategy, brand, research, market sizing, messaging, positioning, product marketing, social media, content marketing, PR and earned media, grassroots marketing, and the list goes on. Within each of these topics there are many different approaches and philosophies. High-level pop books will be fairly light on how each of these work.
