I read the book by C.S. Lewis some years ago. I would be interested in finding more fiction or nonfiction works offering relatively contemporary perspectives on the experience or functioning of dark forces within lived (e.g., practiced or historical) Christian faith.
For example, I would like to be made aware of an ostensibly nonfiction polemic specifying how FDR's New Deal appears to have met the criteria for a work of the devil; and I would also like the book list to identify a fictional piece visualizing Satan in the halls of FDR's White House.
The problem is, I don't know how to characterize what I'm searching for. I seem to lack a name for what this literature would be called. For instance, Warnke's Satan Seller would be within the scope of my interest, though it is not an apologia or otherwise obviously similiar to The Screwtape Letters, beyond its generally satanic orientation.
Satanology comes to my attention, but I don't believe I'd want to get bogged down in the theology of Satan. I'm relatively familiar with biblical remarks on the subject. I'm looking more for arguably real-world elaborations or applications - for material that might tell me something I haven't already heard. But what is a name for that body of publications?
