This is a fascinating series by the Dallas Morning News about Texas' Aryan Brotherhood gang, their drug trade, and a female member who turned informant. Once you start this you will find it hard to put it down. It is a great look at both crime, criminals, informants and law enforcement use of informants. It is also a compelling human interest story of the young girl whose early adventures into sex and drugs led to a very troubled life and becoming an informant. You will not be disappointed.
