Why does Enrique become the "most famous undocumented immigrant in America"?

Enrique’s Journey first appeared in 2002 in the Los Angeles Times, as a series of six articles written by Sonia Nazario, with accompanying photographs by Don Bartletti. Both author and photographer were awarded the Pulitzer Prize for their work. Nazario later expanded the article into a book, which was published by Random House in 2006. Since then, Enrique’s Journey has won numerous book awards, and is on the required reading list of a number of colleges and high schools across the country.
