FYI: Samuel Logan's (of ISN) narrative non-fiction work This Is For The Mara Salvatrucha is being published in July.
This is a true story of Brenda Paz's last three years of life as a member of the Mara Salvatrucha, or MS-13.

She was a young member of the Mara Salvatrucha, or MS-13, who became a federal informant before she was killed after running away from witness protection. This book uncovers little known truths about the MS-13, one of America's most violent street gangs, and reveals how the street life can be alluring to even well loved kids like Brenda.

This narrative also takes a close look at the the realities of living inside the United States as part of a Latino immigrant community, underscoring the challenges with policing these communities and the fluidity of illegal movement across the US-Mexico border.
SWJ contributor John Sullivan's endorsement is quoted in the promotional material:
"Logan captures the ethos and lethal brutality of Mara Salvatrucha in his groundbreaking case study...The insight presented here adds depth to the discussion of the maras and the networked nature of gangs, their members and cliques in a way that facilitates an understanding of contemporary transnational gangs."
