I had a really hard time with this book.
Content-wise, the themes of this story were so captivating as discussions of toxic masculinity, machismo, and violence against women were brought in the context of a southern Mexican setting, with horrible horrible main characters. The authors use of vividly decrepit and disgusting imagery really encapsulates the absolute horrendous nature in which these men think, and the motives behind their decisions. Ultimately, however, to understand them is to understand the culture they are brought up in, and to understand how they feel indebted to life simply due to their gender. 
As a Mexican American woman, this book tackles ideas I know all too well. 
While I have much to say on the content of this book, I found a lot negative in the formatting and translation in the book. I had so many issues following the lengthy run-on sentences, and found myself skimming through parts I deemed uncomfortable. I found some of the babble to be unimportant at times, and hard for me to care about. Very violent depictions of women, while necessary in the context of the theme of this book, were at times so gruesome they became nauseating and had me feeling upset, needing time away from the book.
Overall, I cannot see myself giving this book over a 3.5 because of the above mentioned.
