Highly Recomned THE SECRET OF NEW YORK REVEALED by Thomas Howard. The Forward by Fr. Benedict Groeschel alone is worth the consideration.
Howard's book is based around finding the Holiness in everday life. A very large theme in the writings of Charles Williams (an major "Inkling"). Howard, while doing his Ph.D on Williams in NYC, discovers the "Secret of NY City".
Wow-what a flowery description of New York City! I could imagine some unknowing soul hearing this-they'd think New York was like a huge Seminary! When they got there they would see the rats, crime, debauchery and filth that this city is truly famous for!
