I enjoyed this enormously: I liked the juxtaposition of multiple different cultures and societies. The premise was intriguing, the kids are resourceful, the parents believable, the robots were funny. Good set up and good payoff. I would thing this would be insanely popular since it's like to appeal to fans of fantasy and science fiction, to horse people and
Western people, everyone really, except aliens.
My only problem with the book is a technical detail: I had tremendous trouble reading the speech sometimes. Yes, I'm old and the eyes go and dim lighting isn't sufficient anymore et cetera, et cetera, but none of that troubles me when reading anything else. I'm not confident I know what the difficulty was: whether the book pages were too small (for me), or the font size too small (for me), or the contrast not sharp enough (for me). I can't say with any certainty. But it made for an uncomfortable experience. I'm a motivated reader, so I stuck with it, but I can imagine that not everyone would. YMMV
