Started so well for me with a real relevance to current world and Middle Eastern events. I'm afraid I tired of this and was willing it to end. The author uses a device of having the protagonists consider each other's motivations. Almost always, in these reflections they seem to have a perfect understanding. Unfortunately, this adds up to repetition of the same content.
In the end, this finished with a whimper and I feel well rid of it. A shame.
