G-Dog and the Homeboys: Father Greg Boyle and the Gangs of East Los Angeles
by Celeste Fremont
This book is the story of Father Gregory Boyle and his work with the gangs. It is mostly a journalistic account, but the author does also discuss how her account cannot be wholly impartial, as after following Father Greg and some of the gang members for four years, she grew to care about what happened to them, as well as to want to alter the course of events in their lives for the better.
After reading Tattoos on the Heart, I wanted to know more. This book filled that role. I recommend it to others, but if you were only going to choose one, Tattoos on the Heart would be it.
