The book is called Verse and Poetics in George Herbert and John Donne. It's about two seventeenth-century poets and their commitment to poetry as a culturally and theologically privileged mode of expression. If you want to read more about it, the best place is the publisher's own website, though personally I find it more thrilling to view it on Amazon.
PS An e-version was also published, but an online search suggests that the author of the ebook is not in fact me but someone called (much more excitingly) Cecilie Vindal Odegaard. I assume this is someone who works for Ashgate, but I'm also thinking seriously about assuming it as my own nom de plume.
