I cannot wholeheartedly recommend Steven Pinker’s style-guide / usage manual, but it does have a couple of important things to say about written English.
Respect Your Tools
Language has its own internal logic. Good writing respects that logic. Writers should study grammar explicitly rather than rely on intuition in order to communicate clearly, show respect for their readers, and inspire confidence in their work. Good writers are those who read widely enough to absorb good practices from a longstanding written English tradition. They know the rules but also when to break them.
Break the Rules
The Ancient and Venerable English Teachers’ Code—beloved by Grammar Nazis, Prescriptivists, Fussbudgets and Curmudgeons—is more what you’d call guidelines than actual rules, and some of the guidelines will lead you astray because (a) Some were written by people who didn’t understand English and (b) Thanks to natural and inevitable language change, the English we use today differs from the English of the past.
