Who’d have thought that a Ferrari-racing, no-questions-asked gold trader like Ben Raab could be laundering money for a Colombian drug cartel? Well, not his daughter Kate. She chooses boyfriend and career over following her family into Witness Protection, sniffles over shattered illusions — ”Who the hell are you, Daddy?”— and dodges vengeful Colombians in Andrew Gross’ The Blue Zone. Worse than the sniper fire is the emotional impact that hits clueless Kate ”like a fist in her abdomen,” ”like a punch deep into her solar plexus,” or ”like some meteor slamming into her.” Oof! Alas, Gross’ flabby first potboiler without partner James Patterson won’t floor readers with its trite revelations.
