This is the second book by Oscar Zeta Acosta, the Chicano lawyer immortalized as Dr. Gonzo in Hunter S. Thompson's Fear and Loathing in Las Vegas. The book is a semi-autobiographical fictionalized account of the Chicano Moritorium, a movement of Mexican-American anti-war activists that formed a coalition to organize opposition to the Vietnam War.
It's been a long time since I've read it but I do remember enjoying it, and this is a particularly nice copy and edition (the first, actually!).
Much like the blood splatters in Fear and Loathing, the book is "infested" with random cockroaches crawling around the pages.
