One of the great small book I read about writing is: Style: Lessons in Clarity and Grace (https://www.amazon.com/Style-Lessons-Clarity-Grace-12th/dp/0134080416 https://www.amazon.com/Style-Lessons-Clarity-Grace-12th/dp/0...) It is very different from Strunk&White book in that it does not address things like whether you should place a comma or not, it teaches you about how to present you idea clear and easy to understand. In short write less like Friedrich Hayek and more like Ray Dailo. The former uses much more beautiful long sentences, but the latter's essays are more easy to read, and clearer in delivering the author's ideas.
