I have Prairie Fires, but inexplicably haven't actually read it.
I remember reading the books for the second or third time as a child, and my mother was also reading them for the first time. I remember her commenting how hard it must have been for Caroline/Ma - every time they were just getting settled, Charles/Pa decided they should move on, and she just had to go along with it, never getting properly settled. I remember thinking, but it was so exciting, all the adventures and everything they saw. But now I am an adult who us responsible for keeping a roof over my head and food on the table and so on, I can see how she must have longed for more stability and certainty.
I too think Laura felt restricted by gender expectations, needing to sew and so on - but though she was educated and had her own career as a writer, she wasn't really a feminist; she just grew up in a time/situation where everyone was expected to pull their weight.
I recently read Rose Wilder Lane's diary from being a nurse in France in WW1 - Laura raised a remarkable daughter, too.
One day, when I have money and travel is allowed, I'd like to go to the USA and see some of the places LAW lived in - quite a few have museums. I suspect otherwise, places like De Smet are not very interesting, but it would be a way of seeing a less-touristy view of the USA.
And if it hadn't been for LAW, I would probably not have read round the subject of 19th century US history as much as I have, nor have as good an understanding of where different US states are.
