As to the the decried Christian Fiction genre:
Anybody with an open mind and a hint of curiosity can at any time find a dozen such freebies at Amazon. Pick one with a 4-5 star rating and see for yourself.
Most come from smaller publishers but some can be found from Harlequin and other larger publishers seeking to tap this particular counter-culture.
What you'll find is most likely a straightforward romantic comedy or family drama where the protagonists *don't* start "bonk"-ing at the drop of a hat, don't curse or do drugs, rarely drink, and are all earnestly religious and community-oriented. Hard-working people who are tolerant of other religions, help each other out willingly, and are generally pacifist. (No alien invasions, glittery vamps, or zombies... to my, admittedly-limited, knowedge.) Not too many LEFT BEHIND's in there.
They're just harmless fantasies (in the broader sense) for people who find mainstream culture gross and offensive and who prefer gentler time killer reads.
Let's see now...
Here's a sample, check the reviews:

It may not be John Ringo but I see nothing there worth disparaging.
