Blood in the Fields also documents the history of Operation Black Widow, the FBI's questionable decade-long effort to dismantle the Nuestra Familia, along with its compromised informants and the turf wars it created with local law enforcement agencies. Journalist Reynolds uses her unprecedented access to gang members, both in and out of prison, as well as undercover wire taps, depositions, and court documents to weave a gripping, comprehensive history of this brutal criminal organization and the lives it destroyed.
