Love in the Details

How to break into a new-ish genre for me, Christian romance? Venn diagram book bloggers' recommendations and my library's catalogue.
I finished it, but...
This isn't an author I'll read more of. My quibbles are various and serious.
The Christian faith of the MCs seemed decorative rather than fundamental to conflict/character/plot. The book would have been better for me without it as a flourish. It was confusing to me: faith and prayer are interesting, complicated, vivid, surprising in my own life; here they seemed like a think cultural veneer that just went along with the setting rather than a source of character development or conflict/resolution.
The shallow use of faith matched shallowness in supporting characters and main characters. The h's best friend was a thinly painted character (perhaps she had her own book and I missed it?) with a nameless husband who did all the home chores so she could be an indulged princess (yuck!). Friend's advice to the h on how to get a man included wearing tighter clothes and getting gel nails. (You should see the expression on my face as I recall this because–...???!!! What the WHAT??) The main plot-turning actions of the characters also seemed kind of arbitrary and not arising from genuine character development. IOW, I didn't believe that these people were people, but rather paper dolls moved around by an author through a pre-plotted outline.
Why did I read the whole thing? It wasn't horrible.
