Synopsis All hail the bacchanalia that is the glorious tradition of spring break in Neptune, a time for scantily clad beachgoers to get loaded, laid and murdered. When a series of fatal bomb blasts threatens to decimate the seaside town's tourist industry, Mars Investigations is hired by a wealthy congressman to track down the killer of one of the victims. As Veronica navigates new developments in her longtime relationship with Logan, she's sucked into a dangerously complex mystery that pits anti-spring-break elites against working-class townies and stretches from Neptune's pristine paradise into U.S. politics and a Mexican drug cartel. But never fear, Marshmallows, Veronica's back -- and she's still fighting mad!
