I think this would best be described as Gonzo journalism, in which the writer embeds herself in the struggle of the Mothers of the Plaza de Mayo, losing all objectivity and including first-person narration. The style of the book, exploring aspects of the Mothers' struggle and campaign, brought up a lot of fascinating parts, and it was a great source for a paper I'm writing quotes-wise, but I think that it included far too much editorializing throughout. One point really annoyed me, when Bouvard spoke about the youth group that the Mothers associated with, painting them as corrupted by the Left in the way that she argued the media had previously done.
I do appreciate, however, that Bouvard included some quotes from critics of the mothers (though she immediately refuted them), going over their reasoning, even if many were government sources. It's interesting to see the complex dynamics of Argentinian politics, and their unique parties and tensions. Bouvard includes a lot of history and background on the Dirty War which was useful for my essay and interesting in general.
Bouvard is also clear in her source citing and notes, with a wide array of sources — from newspapers to the Mothers she interviewed to the government law. I do think that at times she should have been clearer in what is the Mothers' views and what is her own opinion, as at times it got to editorializing.
But overall, this was a really interesting read, and very helpful for my project! I learned a lot.
