Read the excerpt from Enrique’s Journey. During his first attempts north, a chance meeting saved Enrique from the worst of the gangs. As he set out on his trip, he noticed another teenager, a gangster named El Brujo, at the bus station in Honduras waiting to go to the Mexican border. Enrique doesn’t like gangs. But as the two spent hours traveling through Honduras and Guatemala together, they became friends. On their first train ride through Chiapas, El Brujo introduced Enrique to a dozen other MS members, among them Big Daddy, who is skinny and short; El Chino (the Chinaman), who has slanted eyes; and El Payaso (the Clown), who has a big mouth and eyes. On subsequent trips, when he was deported, he always stuck with one of these gang members to protect himself from any attacks.
