Revenge: it won&rsquo;t bring your wife and kids back, but it might help with the nightmares.<P>Patricio Carrera has been waging what amounts to a private world war to bring to justice the murderers of his family. He&rsquo;s raised an army and air force and used them. He&rsquo;s raised a fleet and he&rsquo;s about to use that. He&rsquo;s suborned one republic and is about to undermine another. He&rsquo;s tracked his enemies across half a world, breaking, in the process, any notion of international law that stood in his way.<P>Now he&rsquo;s deployed his legions to Pashtia, penultimate hideout of the <I>Salafi Ikhwan</i> who have made him what he has become. But with each step further from his home, revenge seems no closer. And with each step he leaves behind him a little of his dwindling humanity. <P>Revenge is a dish best served cold. Yet the trail itself grows cold, as cold as the snow-capped, windswept mountains of Pashtia. Only Carrera&rsquo;s hate still burns hot, and that&rsquo;s a fire that is slowly consuming him.
