Hmm, considering your religious upbringing you might want to try some absurdist literature to break the mold.
The Hitchhiker’s Guide to the Galaxy
The Cyberiad
Discworld
The Little Prince
These are accessible too, as you’re not used to reading yet.
I can also recommend subscribing to a monthly magazine and making a point to read it from cover to cover. That way your skills will improve. You can also buy a whole stack of old national geographics cheaply. This will expand your horizons.
