How then can she refuse when a rival taxi company hires her to investigate the assaults? Thinking she will be making the world a safer place for cab drivers, Carlotta doesn't suspect that this new case will push her even closer to the edge. The company she works for is co-owned by Sam Gianelli, her sometime lover and a mob-connected businessman whose family knows how to get tough. Drawn into a tangled conspiracy of mafia secrets and high-tech espionage, Carlotta will have to drive faster than ever to stay alive.
