We spend, in reading this novel, a good time. A write both easy and enjoyable, content both exciting and somewhat disturbing. All these elements are characteristics that can be found in general in the novels of JC Rufin. A simple novel, but well written, without unnecessary claims, without giving any warning that lesson, affordable by any player and yet pinpoints a danger rather unknown but real, that of eco-terrorism. Elements found in this novel (but treated completely differently) the beautiful novel by TC Boyle "A friend of the earth." The harmony between man and nature can it be achieved? Is the man the most dangerous predators? Who should we save? About an interesting and intelligent, in a captivating plot.
