Crossing a border is portrayed as a tough thing in the movies and in reality it is tougher than it seems because you are not a hero of course. Crossing between the US and Mexico is no child play, death seems to be moving behind you with little cat feet ready to pounce on you. Slightest mistake can take the dream away along with the precious life that you tend to make better.
Jeanine Cummins talks about a girl named Lydia who had a good business once and a loving husband, the two things that a woman usually dreams of.
That is all a thing of the past now because Lydia has lost big in her life and now she is not ready to lose the one thing she is left with i.e her son. For him she is ready to be the hero that she never tried to be in her dream but there is nothing she can do now.
Lydia has a knife tied to her leg which means she will fight for sure with whoever stands in her way. Crossing the border illegally was not part of her plan and now she is on the roof of a train with all eyes set on the target. When you are crossing the border you have to run and only a bullet in the head can stop you for good.
This is what she is telling herself now again and again. Author has talked about hardships before in novels like A Rip in Heaven and The Outside Boy but here the author has written the whole procedure of illegal migration.
The tough situation of the people migrating can be felt in the voice of Yareli Arizmendi. The narrator shows through the voice the injustice that is done to the people in the US as the government treats them like useless creatures because they are a burden on the state.
