Book excerpt: Adventure fiction. Suspense fiction. Science fiction. From the author of "Go the F*** to Sleep". Raised in the shadow of two graffiti legends from New York's "golden era" of subway bombing, Dondi Vance is less than thrilled to learn his father, Billy Rage, is back after sixteen years on the lam. But the transit cop who ruined Billy's life and shattered his crew is running for mayor-and must be brought down.
