Although Pariah won't be hitting the US for 5 months (other than through copies now being leaked by amazon), Nathan Cain offers a review over at his Independent Crime blog.
Zeltserman has succeeded in bringing a blithely psychopatic character to the page who will chill the blood.
Despite the utter moral bankruptcy of the main character, Pariah is gripping as opposed to repugnant. Zeltserman's writing and plotting are sharp and the plot is immaculately crafted. The only other author writing about such venal characters with such an incisive eye is Jason Starr, and some of Starr's characters are downright cuddly when compared to Zeltserman's. Pariah is a scathing rebuke of society's obsession with fame, and mythologizing of gangsters and the repugnant moral calculus that allows them to victimize innocent people with impunity
