American Libre author Ramos y Sanchez offers myriad perspectives on a civil war in his slushy latest. War has ravaged a Los Angeles where people who are designated "class H"--Hispanic, married to someone Hispanic, or having at least one grandparent of Hispanic origin--are carted off to quarantine zones. As a violent uprising stirs, Manolo Suarez, who has already lost a son to the war, fears for his other son, 13-year-old Pedro, who falls under the spell of a charismatic gang leader. As Manolo fights to keep his family safe, a slew of story lines sprout: two U.N. delegates of Hispanic origin with opposing views on how best to support their people, an ambitious C.I.A. operative, a young officer hell-bent on proving himself to his superiors. Unfortunately, Ramos y Sanchez neglects his characters' psychological and emotional development and instead leans heavily on potboiler plot twists and dialogue that too often slumps into action-movie banter. The novel is unfailingly earnest and moves confidently enough, but the treatment of conflict and its aftereffects is too shallow to resonate. (Jan.)
