What I found interesting? Delving into the lives of two agents, or two terrorists, whichever way. Personally, I couldn't agree less with any school of thought that can tag one as an agent and the other as a terrorist. The process of self justification was interesting to follow in both cases, because unlike most media representation, it was quite undramatic, and rather matter of fact. The real brand of self justification, if you will.
What I did not like? The writing. I was warned, and yet, here I am, making a point of it. The reason I could feel engaged had everything to do with the story, rather than the story telling. I wish it could have been better, but I suppose non fictional narratives are not exactly expected to be superlative that way.
Better prose could have added nuance; on the other hand, it could have taken from the sheer, bland, candour, imperative to such narratives. It's a tough debate.
I give it a 3, because while it kept me intrigued enough, there were only rare occasions I found it flattering.
Do I recommend it? The world we live in is making history for the world in the making, like any world past. Sylvia Rafael is a story of many stories, that are important links in that history. If that interests you, this is a book for you.
