According to "The Review" chapter in "Political Writing" by Adam Garfinkel, a book review is "an attempt to persuade based on an attempt to persuade". Assuming you are interested in persuasive writing, I'm going to attempt to persuade you to buy this little book. ("Little" is the author's adjective.) Even though only "Political" is in the title, the book is about persuasive writing. If you want to be a more effective persuader in writing or speaking, politically or otherwise, you should read and heed this book.
The author has taught the subject at university level. His material shows its class-note heritage, with reading assignments and exercises for each chapter. He has practiced the craft of persuasion for his own benefit and that of others in academia, in government and the press. Don't expect dry lectures and only ancient references; Copyright is 2012. His examples, chosen from famous and not-so-famous people, sparkle with insight and challenge with goals to emulate. Specific chapters contain tools and tips for every conceivable venue of argumentation from essays to op-eds to blogs. His chapters on better writing cover not only the how, but also the why.
The only missing reference is [[ASIN:B00849DOU2 Birkenstein's, Graff's The Moves That Matter in Academic Writing (They Say/I Say: The Moves That Matter in Academic Writing by Gerald Graff and Cathy Birkenstein (Paperback - Jan. 10, 2006), available from Amazon in print and Kindle. Although some will scorn the Graff-Birkenstein template approach, the templates complement Garfinkel's exposition and can be the friend that he recommends in his segment on Writer's Block.
