Below is my scholarly article on how Christians can engage critically with science fiction. This is written for you, the well-read layperson or academic. (It’s published in the peer-reviewed journal, Christian Scholar’s Review, in July 2019.)
The article tries to merge the basics of existing academic critical concepts with Christian perspectives on reading, God and creation.
If nothing else, you’ll find plenty of recommendations in this article — good critical books on science fiction, and great science-fiction books.
