Note, May 27, 2021: I just edited this review slightly to correct a minor typo.
Despite the cover image of a young woman with a Colt on her hip, this novel, set in the mining country near California's Mohave Desert in 1883, doesn't feature the kind of motifs and gun-fighting action typically associated with the "Western" genre. I've classified it as historical fiction that happens to take place in the late 19th-century American West. (The image, though, is legitimately taken from the book; heroine Abigail does strap on her dad's holster for personal protection at one point, when she needs to visit a saloon, and by her own statement she's a good shot, though she's not obliged to demonstrate it here.) Expectations created by the title, though, would be accurate; the heart of the plot here is a naturally-developing clean romance. It's not, however, what I'd call a sappy romance, and offers some content and plotting besides the romantic angle. Guessing correctly that it would be right up my wife's alley, I bought a copy as a gift for her a few years ago (being admittedly captivated by the cover myself --that won't surprise anybody who knows my tastes! :-) ); she'd read and liked it then, and was up for a reread when we were recently looking for a new book to read together.
This both is and isn't a "series" book. The publisher has a whole line of novels with the title Love Finds You in ______, the blank filled with a real-life place name. (This is the only one that I've read, or intend to read.) Otherwise, the books are unrelated to each other and self-contained. That use of actual settings functions as a sort of gimmick, and presumably usually appeals to current or former residents of the localities featured. Calico, though, is probably unique among these in that it doesn't have any current residents as such; from 1881-1896, it was a thriving boom town with a mining-based economy, but the playing out of the mines sent it into rapid decline, and it was deserted by 1904. Walter Knott of Knott's Berry Farm purchased the site and ruins of the ghost town in 1951 and began to restore it as a tourist site, and today it's a publically-owned park and tourist attraction. Author Ludwig stumbled on it during a road trip, and seriously researched its history for this book; but while she tried to keep the flavor of the community accurate, the characters and events are fictitious. (However, Dorsey, the mail-delivering dog, really existed --and dog-loving readers will appreciate that he plays a key role in the plot.)
As is sometimes the case, I don't recommend reading the Goodreads description (or the cover blurb, which as is even oftener the case, Goodreads simply reproduces); I think it gives away a good deal of the plot that readers would prefer to discover, and the author would prefer to disclose, in the natural course of the reading journey. Suffice it to say that we have a romance between a single woman and a widowed man with a small daughter (that's not a spoiler --it's not hard to guess who Abigail's love interest will be). This plays out against the backdrop of a slow-burning mystery that surrounds a fatal mine fire --although I didn't classify the book as a mystery, because the stupidity of the culprit removes the need for much detection-- and is complicated by the failure of both to honestly express their feelings, and their willingness to jump to wrong conclusions. (As my wife points out, this is actually true to the way all too many real-life humans really interact; but I still find it a frustrating and overly common device in "romance" fiction.) I would also fault Ludwig for the fact that one key conversation between hero Nathan and a couple of other characters, which should have played a major role in the tale, is simply dropped afterwards and might as well not have occurred. But I give her credit for highlighting the discrimination against Chinese immigrants in that era, for depicting cross-racial friendship, and for good character development and portrayal of human relationships (not just of and between the two co-protagonists). The denouement is also exciting --it has Abby in damsel-in-distress mode, but shows her taking a hand in trying to deal with the situation herself, not just sitting around hoping to be rescued. Though Ludwig is an evangelical Christian author writing for a Christian press, I wouldn't call the book "preachy." It does show believing characters wrestling believably (as they do in real life) with the fact that good people sometimes die seemingly prematurely and that prayers aren't exercises in wish-granting, but who also take Christian ethics seriously and don't abandon hope and trust in Divine providence.
