Un Tren Llamado Esperanza/ A Train Called Hope

Years later, after his parents have gone far away in search of work and a better future, the boy rides in a real train to join his family. This one is loaded with hundreds of children traveling alone, just like him. There are frightening strangers, others along the way who want to jump on and, scariest of all, a boy who almost falls off the roof because he can't stay awake any longer.
