The body of an African American high school student in Mobile, Alabama, in 1981 is discovered by Paul Deacon, son of a prominent black funeral home director. Initially, three drug addicts are accused of the crime, but the case against them quickly falls apart, and no progress is made for several years, even though it is obvious that local Klansmen are the murderers. Paul's brother Roy recalls these events 20 years later as a grown man with a family of his own. Howard's novel is not primarily a whodunit or a police procedural, although it does have a strong CSI slant. The subject is really the city of Mobile and the rapidly changing Gulf Coast community two decades after the major struggles of the Civil Rights era (Library Journal).

This sounds like a great read and was recommended by noted award winning author, David Anthony Durham of "Gabriel's Story," "Walking Through Darkness," "Pride of Carthage" and soon to be released (June 2007) fourth novel "Acacia" a speculative novel set in an alternative world.
