Hurwitz (Last Shot
) blasts new life into a well-worn theme—the prominent politician trying to hide a dark incident from his past—in this intelligent thriller. Late one night, the Secret Service snatches 36-year-old Nick Horrigan, who's led a quiet life since making a fatal mistake in his teens, and whisks him to the San Onofre, Calif., nuclear plant. There a terrorist threatens to set off a bomb unless he can talk to Nick, who hasn't got the slightest idea why he's been summoned. After the terrorist gets his head blown off, Nick realizes this and subsequent events are connected to the death years earlier of his Secret Service agent stepfather. Working with his homeless pal, Homer, and his computer whiz ex-girlfriend, Induma, Nick pieces together a string of clues that point to a paternity case against either the U.S. president, Andrew Bilton, or Sen. Jasper Caruthers, Bilton's opponent in an upcoming election. While more astute readers may intuit the bad guy, Nick's ethical dilemmas, girlfriend dramas and sleuthing provide plenty of excitement.
