I read this for my second-year Spanish courses and was surprised by how much enjoyed it. There's more sensitivity to indigenous / colonial topics than I expected… although I admit that my bar was on the floor regarding those. I'd be interested to eventually read the original, un-adapted novel—and well as to learn whether this influenced the 1980s/1990s cartoon I vaguely remembered titled something like "City of Gold" that might have been on Nickelodeon.
