There's really not a weak story here; they often feel worth reading on the sheer brashness of their Kilgore Trout-ish premises, but the writing is strong even in the quieter stories. Fantastic, science fictional, and magical realist techniques flesh out ideas and characters that are almost uncomfortably, clearly drawn from present reality.
"The Finkelstein 5", the opening story, launches the collection at full strength. In the wake of a brutal chainsaw-murder of five young black people by a white man who goes free, spontaneous incidences of black-on-white violence erupt while the victims' names are ritually spoken. Both a parody of miscarriages of justice and frighteningly plausible, there's both horror and a kind of bleak, surreal humor in the coverage of the trial. The narrator's storyline captures the confusion and pain around the double violence of the attack and acquittal, and his ability to "dial" his blackness up or down in a quantified way.
