It should be judged by its texture and depth. And for this reason I consider the book to be essential. The prayers O'Connor has written create a landscape for prayer utterly original in the Christian tradition, if also deeply embedded in it.
I am reading one prayer per night, sometimes two. They are leading me into new spiritual insights each time. I see myself in new ways through her prayers.
The book also includes a facsimile of the journal itself. It's really a pleasure to be able to see her hand-writing first hand, to imagine her as a young student writing each day in this journal.
I guarantee if you buy this book, when it arrives, you will do more than read it. You will cherish it.
And a great review by Marilynne Robinson:
