Neither Mason, a U.S. Army Special Forces medic, nor Lisette, a foreign correspondent, has emerged from America's long post-9/11 wars in Iraq and Afghanistan unscathed. Yet war also exerts a terrible draw that neither can shake: the noble calling, the camaraderie, the life-and-death stakes. Mason, now a liaison to the Colombian military, is ready for the good war against predatory narco gangs, and Lisette is more than ready to cover it. Juan Pablo, Mason's counterpart in the Colombian officer corps, faces the challenge of navigating the factions bidding for power, in the capital and far out in the field. Abel, a lieutenant in the militia Los Mil Jesuses, has lost everything he loves in the carnage where the lines between drug cartels, militias, and the state are semi-permeable. -- adapted from jacket
