Setting: Collinsford, Ohio, 1890. The city's size (obviously quite large, and there was even one reference about it being the largest city in Ohio) and nearness to Lake Erie strongly resembled Cleveland, rendering me confused as to why the characters were not just located in Cleveland. Did Miller make up a city name? Nevertheless, I was happy to read a book set in Ohio. The factory lifestyle, contrasted with high-society life, was well portrayed and didn't feel forced.
Characters: Not entirely likable on the whole, but they did have distinctive personalities and quirks, and they didn't irritate me to an extent that I didn't enjoy reading about them. Carrie had her flaws, but she also had an earnest desire to replace her flaws with virtues, so I had grace for her. But boy, was her pride an issue. It was interesting to have pride be a major development point for a character, and I liked the uniqueness--even though prideful people are extremely annoying (even if they are right, which in Carrie's case, may have been about 60% of the time). It was a good reminder on how one should act in real life.
Josef was a pretty good character, with fun character distinctive. He was lacking a bit, possibly because he never had a POV; therefore, from the romantic perspective, his attitude changed rather inexplicably. It wasn't altogether rushed, and therefore it wasn't that noticeable, but the he lacked a romantic punch.
Augusta, her parents, Mrs. Wilson, and Mr. Lundgren were all fairly well-developed, if not exceptionally endearing, but that's just a result of the story and their involvement. I actually did end up liking Mrs. Wilson a lot--she actually had a remarkable character development. The more annoying characters were Detective Lawton and Tyson, and for the same reasons, except in the end it was quite different. Both personalities helped develop Carrie's quite well, but I wish things would have been resolved better to further establish Carrie's finished character arc.
Plot: On the surface, it was an interesting mystery combined with a nice romance, and some humorous dashes thrown in. However, being the nit-picky analyst I am, I soon found some unsatisfying parts. Carrie's character arc didn't finish out well, as her problem--her specific issue of pride--was soon lost in the general resolution of becoming a more mature Christian.
There was also a weakness in the romance part, in that the initial tension was not directly resolved. Then at the end there wasn't such a strong resolution. It felt that the romance was more of a garnish than a plot aspect--or rather, a stepping-stone to the resolution to the main plot, which was the mystery.
The mystery took priority in the end, not so much of the solving of the mystery, but more for its inconvenience on Carrie's life. That was not how the beginning is written, so the plot ended up being rambling, even though all aspects were interesting.
Faith Content: I already mentioned that the issue with Carrie's pride wasn't resolved very strongly or specifically. But in general, Carrie's spiritual development was nicely done. I appreciated how the utter difficulty of "being a good Christian" is portrayed. Josef's struggle was particularly relatable. The preacher's sermons were frequently included, but there was a nice balance of straight teaching and Carrie's reaction to the teaching. The balance of Christian and non-Christian (or at least seculars in a Christian society) was also nicely done.
All in all, I enjoyed reading the book in the moment, for the intriguing plot and obvious flaws that needed to be resolved. In hindsight, though, the plot was just not very tight, and there were a few holes in the story.
