I have just sent in a review for the Journal of Church and State (Baylor University) on Brent Nelson's Holy Ambition: Rhetoric, Courtship, and Devotion in the Sermons of John Donne. First and foremost, I want to congratulate Brent on writing such an excellent and thorough examination of Donne's rhetorical strategies for the sermons. The book is available from the Arizona Center for Medieval and Renaissance Studies (38.00$ cloth), and is well worth its price.
