Having grown up outside the US, I never read these books as a kid, and they're actually very interesting as an adult still learning about the country. In fact, I'm not convinced this should be a childrens' book, because being written from a small child's perspective means it only vaguely hints at the evil backdrop of the story. But the first-person perspective brings the experience of being a Pioneer much more alive than any historical text I've read, and as someone who very much buys into the "the Pioneers perpetrated gross acts of ethnic cleansing" view espoused by that linked article it was actually kind of refreshing to read an account that humanises them.

This book romanticises the Pioneer life considerably, but not to the point of airbrushing out all the difficulties and discomforts, and it was actually a lot less of a propaganda tract than I had expected it to be. Definitely worth reading as an adult, with knowledge of the background.
