Two of today's sunniest authors come together for a dystopic evening of apocalyptic proportions. Nersesian's Mesopotamia is a full-bodied noir in which a journalist digs into a series of Southern small-town murders. Sharpe's Jamestown, with its war-seared landscapes, survivalist overtones and visions of eco-unfriendly endtimes, reads like an idiosyncratic companion to Children of Men and Cormac McCarthy’s The Road. Bring your own Prozac.
