The Silence of Our Friends by by Mark Long

This semi-autobiographical tale is set in 1967. A white family from a notoriously racist neighborhood in the suburbs and a black family from its poorest ward cross Houston's color line, overcoming humiliation, degradation, and violence to win the freedom of five black college students unjustly charged with the murder of a policeman. 
The Silence of Our Friends follows events through the point of view of young Mark Long, whose father is a reporter covering the story. Semi-fictionalized, this story has its roots solidly in very real events. With art from the brilliant Nate Powell (Swallow Me Whole) bringing the tale to heart-wrenching life, The Silence of Our Friends is a new and important entry in the body of civil rights literature.
