A young man came to the United States when he was seven months old, tucked under his mother's arm as she crossed the border between Mexico and Nogales, Arizona late at night. He says he remembers it, but of course he doesn't. What he remembers is the story his mother told him. It has become his own narrative, as much a part of his identity as his Brooklyn accent, his low-slung jeans, his endearing stutter and his love for computer games. He is now 20 and has spent all of his life, except for those first brief months in Puebla, in this country. He is 100 percent American, or as he puts it "100 percent minus seven months" American. He loves this country, girls, school, classical music, and his parents who sacrificed everything so that he could have a better life. He also loves his three brothers and two sisters, all of whom are American citizens.
