This is not a view of the persons trying to enter the USA from Mexico as it sees the cynicism and inherent capitalism that affects non-rich human lives. This is a first-person depiction of the war which rages from the USA against Mexicans, the group of nationality which is most abused in everyday northern America, and is being "thwarted" from entering the USA.

Cantú worked as a US border patrol agent between 2008 and 2012. As such, and seemingly being an open-minded humanitarian, he's seen a lot of shit happen. Everything from finding half-dead persons dying from thirst while trying to (illegally) entering the USA, to seeing border politics basically going from there not being a border, to capitalism of the 1980s entering the picture, to how Bush/Obama/Trump want it all to be, caused a state where US border patrol is made up of persons who want to protect their country with pride, while behaving like human beings towards those trying to get into the US.

Still, as such, violence and callous behaviour is often normalised, as is violence towards border patrol staff.

Cantú is a born writer. His level-headed style of description, rhythm, and laying out facts is both seldom seen and deeply valuable. I'm left with a sense of enrichment from having read this book, even though I have read a bunch of others that have been about trafficking around different parts of the globe; his human views and views on humans provide the reader with ample info.

The slightly bad side with this book is that the facts pile up almost like a kind of fact-after-fact recount, which novice writers can be prone to delve into. Still, considering how this is the author's first book, it is a veritable tour-de-force which should receive more press than it has.

Examples of the short and packed sentences:

Robles’s eyes seemed to detach from his surroundings, as if his gaze had turned inward. A year after that, he continued, I chased another man to the banks of the Colorado River. He ran out into the water and was swept away by the current like it was nothing. And I’ll tell you what I did. I swam into the river and I battled to keep him afloat even as I inhaled mouthfuls of water, even though I can’t remember ever having been more tired. I saved that man’s life, and still, there’s not a single day I don’t think about the one I took before it.

The writing that's not entirely about patrolling is also good:

After completing the course of fire, I shot at a smaller target with my own .22 caliber pistol. As I paused to reload, a yellow bird landed atop the target stand. I waited for it to fly off, but the bird continued hopping across the top. I started to walk downrange to scare it off, and then I stopped. I looked around. The range was empty. It occurred to me then that perhaps I should shoot the bird, that I should prove to myself that I could take a life, even one this small. I dropped the little bird with one shot. I walked over and picked up its body and in my hands the dead animal seemed weightless. I rubbed its yellow feathers with my fingertip. I began to feel sick and I wondered, for one brief moment, if I was going insane. At the edge of the firing range I dug a small hole beneath a creosote bush and buried the bird there, covering the fresh dirt with a small pile of stones.

I liked this bit, which probably best of all paragraphs in the book shows the weariness and paranoia that follows any line of work where one's colleagues and the work is congealed and one doesn't separate easily from that mess:

The dentist silently jotted his notes in my file. So why’d you leave the field? he asked. Won’t you be bored? I began to feel annoyed with his questions, concerned that I was somehow telegraphing cowardice or insecurity. It’s kind of a promotion, I said, it’s a chance to learn something new. Another side of the job, you know? The dentist looked at me and shrugged his shoulders. I used to have an office job, he told me, there’s only so much you can learn at a computer screen. I rolled my eyes and shook my head. Look, I finally said, I don’t know what else to tell you. I thought it would be nice to have a break from the field, to live in the city for a while. All right, all right, he said, holding up his hands. I feel you. I’m just trying to make sure you don’t grind your teeth out.

In summary: an easy read that may reveal more to life than you know where desperation meets bureaucracy in the most insane ways.
