Very helpful. I like that the author seems flexible on what makes good writing. Sometimes books on writing get too caught up in "Writing Rules" or the author's own methods, but the information in Description is clear, concise, and fairly objective. I don't suggest reading it front to back like I did; it was tough to get through because there's so much information to absorb. It might have been more fun to jump around from topic to topic based on what interested me at the moment.
