What is the author's tone in Always Running: La Vida Loca, Gang Days in L.A by Luis J. Rodriguez?

The book is written in a straightforward, easy-to-read tone. There are words from Luis's native language, the Spanish spoken in the barrios. Many of these are self-explanatory or are included in the glossary at the end of the book. Some simply are not and it's left to the reader to either determine their meaning or skip them altogether. There are also curse words scattered throughout the text. These are not prevalent and are used chiefly in dialog where they reflect the speakers and situation.
