With a little knowledge and a lot of practice, you can do more than just sound more professional when you skillfully use commas, semicolons, and other forms of punctuation. You can, importantly, become more persuasive.

That's what students who have taken Professor Patrick Barry's classes at the University of Michigan Law School, the University of Chicago Law School, and the UCLA School of Law have learned, as have the over 100,000 people who have enrolled in his online course "Good with Words: Writing and Editing" on the educational platforms Coursera and FutureLearn.

Now, thanks to this book, you can undergo that same rhetorical transformation. Punctuation doesn't have to be a pain point. When properly mastered, it can be a powerful tool for all kinds of advocates.
