Yes. It's not a regular reading material of mine, but, yeah, once in a while, I'll take a rec from a friend who's really into these books.
When it comes to books, I don't discriminate, I give all genres a try. From light reading to heavy reads, everything piques my curiosity.
Although, I must admit, these novels make for really fast readings as usually, I sometimes skip chunks of parts that seem to drone on and on.
What I find most beneficial about romance novels, versus other genres of novels, like say, mystery novels or thrillers or whatever, with both being comparably equal "fluff" in their own right, i.e., quick light reading caliber ....
is that, romance novels, esp. historical romances or romances in different settings, are sometimes quite helpful in how I acquire information about a new place, culture, practices, etc., quickly, efforlessly and in a light, fun way. I dunno, it seems like the romance novel authors go more indepth to set the stage, so to speak, in a rose-coloured way, and the visuals are flowy. "Romanticized"/charmed (positive spin, I guess).
E.g., I still remember details about Cajun Culture and the Luisiana bayou, the way the homes are in the bayou (on stick legs), etc.; it was the fastest and easiest way I learned of the culture, through a light-read romance novel.
More creative way of learning that reading books that are made for the specific purpose of educating on the culture, which can get a bit boring.
