Edit: Much better review that I posted in the wrong feed initially.
This is more along the lines of a science fiction novel, but have you heard of
Lord of the World by Robert Hugh Benson? Benson was a Catholic priest, a convert from Anglicanism who lived in the late 19th and early 20th centuries.
The book is a reminiscent of a dystopia, such as
Brave New World, but I believe it was written before many of the more famous ones. It is also however, a book that takes place at the end of the world, and because it is (was) set in the future (late 20th century) it has elements of science fiction. It has an unabashedly Catholic view and some beautiful moments. Here are two sites with more information
Wikipedia has a decent article (
en.wikipedia.org/wiki/Lord_of_the_World)
This is an online store that introduced me to the book.

The only problem is that the book, despite being very good and well written, is very hard to find at most libraries. My university had it, but it has a huge library. To finish it during the summer I had to download it online. It is old enough to be public domain so sites like Project Gutenberg have it for download.
I really do recommend it though. I enjoyed it.
