For a funny take on the whole "rhetoric" is the use and abuse of logic some people might enjoy How to Win Every Argument by Madsen Pirie which also happens to be where I plucked the tagline regarding rhetoric from. It's a pretty easy book to go through in toilet break sized increments, the author goes through different fallacies and how they're employed one by one along with various rhetorical devices.
Though a few years ago when I searched for a book on rhetoric and making convincing arguments Office Of Assertion by Scott Crider also popped up, but it's aimed more at written rhetoric instead of what most people have in mind.

But it's much broader than that. You can make true arguments. You can make confusing arguments. And you can use tools that have nothing to do with logic at all. Rhetoric has a lot to say about rhythm, alliteration, and linguistic structure. And a lot more to say about your personal bearing and your tone of voice.
