Sex-Trafficking of Children.

Following Hurricane Katrina in 2006, hundreds of welders and pipefitters were recruited from India to come to the Gulf Coast to repair oil rigs. But when they arrived in the U.S., it was nothing like what they were promised.

In 1993, a freighter with 300 terrified, half-starved Chinese immigrants went aground off the shore of Queens, New York. Author Patrick Radden Keefe chronicles the incident in his new book The Snakehead.

Landesman is a contributing writer to The New York Times Magazine. He investigated the sex slave industry for this week's cover story (Sunday, Jan. 25), "The Girls Next Door." He found that tens of thousands of women, girls and boys are smuggled into the United States from Eastern Europe and held captive as sex slaves in American cities like New York, Los Angeles, Atlanta and Chicago. Landesman reports that the U.S. government has done little to pursue the traffickers.
