In Patricia Lewin's novel of breathless suspense, a shaken CIA officer returns to the field, drawn not by duties but by the chance to save a man's life . . . and to meet the father she hasn't seen in years.

Though Erin Baker has left the CIA, the people who once directed her career tap her to penetrate a medical aid group that may be hiding a sinister purpose. In Cuba, the organization's head doctor is Emilio Diaz, Erin's estranged father. Erin has the skills and a perfect cover to penetrate Castro's shadow world. She also has another reason to take the assignment. An ex-mentor, previously on the case, has vanished somewhere in Cuba.

Full of emotional landmines, this mission comes at a time when Erin's life is at a crossroads. Alec Donovan, a colleague at the FBI, is pushing for more than friendship, and he wants Erin out of the Agency's clutches. But Erin is already in-and though wanting to trust her charismatic father, she suspects that a dark plot is unfolding. Not knowing whom to trust or whom to believe, Erin fights her way deeper undercover until she is ultimately forced to make life-and-death decisions that will affect nations around the world.
