Read the 11th edition - SO helpful for anyone who wants to look at not just WHAT they are writing but HOW they are communicating their ideas. I read this for a college class and it has given me so much to think about when it comes to my writing and personal style. Even if you don't agree with everything they suggest (I didn't), this book is incredibly helpful to make you start thinking about how you can use your writing style to communicate to the reader.
