Please Recommend a Memoir or Biography about Gangs

To my well-read cyber-friends on the Books forum:

I am looking for a memoir or biography that focuses on life in an urban street gang. It must be published after 1990 and if I am really lucky it will focus on a member or members of gangs based in Chicago or any Great Lakes city: Gangster Disciples, Folks, Vice Lords, etc. But you can't really go wrong with the Bloods or the Crips either (actually, you could really go wrong with them, but you get my drift).

I would conduct my own research, go under cover in an area such as Chicago's Garfield Park, but unfortunately I am allergic to murder.

Thank you for your assistance.
