This is a clean, light read.
An Amish Christmas isn't as much of a Christmas novel as I expected, which was actually okay. The main point of the book (that I saw) was how living with the Amish for a few weeks impacted the life of this materialistic, spoiled family. The two teenagers in particular changed for the better due to their experiences in the Lutz household.
Some of the references to technology and current lingo struck me as bumpy, but that would make sense as they were coming from Meg's point of view. There was one, however, that made me laugh. Lizzie, the 15-year-old was talking with Will (who was 13 I think), and he said something about girls with really straight hair. Lizzie responded with something to the effect of, "They use this process to get their hair so straight." Not what she would have said. A real teen would have said, "They just straighten their hair everyday."
I was a little bummed that Meg, this college-educated woman who is obviously very capable is going to bake. And before she had had the dream of going to law school. I'm not really a feminist, but I can't think of one task that was completed by the opposite gender than would be expected. (The Amish aside, even. Meg did ALL of the housework when they were still in Charlotte, and only asked James to get the wine.)
I recommend this to anyone looking for a clean, quick, light read.
