THE GOVERNOR: "Rebound" Rothman, married, family-values New Jersey Republican with White House fantasies, a terrible secret, and a controversial position on young interns: He's for 'em. THE TART: Simone Lava, the voluptuous Miss Little Egg Harbor Township. Rebound keeps her hidden away in Atlantic City's seedy Celebrity Motel where she practices waving like a First Lady, a title she's been promised, if she'll just lay low during election season. THE FIXER: Jackie Disaster, an ex-boxer who runs the Jersey shore's most ruthless damage-control firm. Jackie digs up the macabre truth about the governor. THE POLLSTER: Jonah Eastman, maverick political strategist raised by his mobster grandfather, who gave Rebound his start. Jonah knows only one thing can save the congenitally deceitful governor. A whopping, heartfelt lie. Shakedown Beach rips open the slats of the Atlantic City boardwalk to impart the big lesson of American politics: When forced to look into one's soul and confront the painful truths of murder, corruption and sexual depravity, don't be a schmuck, hire the nastiest operatives money can buy and duck, dodge and spin to November.
