Tracy Wiley lives by two simple rules: take things as they come and levity lightens the load. She’s content in her job as concierge in a Miami convention center solving other people’s problems. She keeps her relationships minimal, including only her beloved father and steady guy Alex Laughlin. All is well until Alex tries to talk about their future and becomes angry when she responds with sarcastic quips. Both petrified by the idea of commitment and devastated by the split, she takes off on a cruise and runs straight into trouble when enigmatic Robert befriends her. Their vacation friendship draws the attention of a government taskforce that recruits Tracy to help catch Robert’s boss, Elena Griegos, head of a smuggling empire and a near perfect twin for Tracy. Masquerading as Elena to help trap her cohorts, Tracy plunges into a dangerous world where everyone has two faces, including the sexy C.I.A. agent assigned to protect her, a glamorous Interpol agent, and a legendary assassin. Even Elena is not what she seems. To regain control of her life, Tracy must swallow her pride and ask Alex for help, only to discover that he too has a few surprises in store.
