The Elements of Style, by William Strunk and E.B. White.
I read several blogs daily, and sometime ago I became aware of two things: I had forgotten most of the basic rules of grammar and punctuation I had learned in school, and that I was not nearly as good of writer as I like to think I am. I decided to change things. This book came highly recommended, and I found it in a used bookstore. We shall see if I learn anything from it.
