Priscilla Metcalf (1915–1989)

Not light reading by any means; this is a very in-depth, technical analysis of the cathedrals of England (ancient and modern) from an architectural point of view. The material was based on Pevsner's series of books on the buildings of England. There's a wealth of photographs and diagrams, and the material is presented logically, though it's assumed the reader has a high level of familiarity with the material. For specialists, but still enjoyable.
