Carlos Bluhm leads the good life in upper-class Lima: He attends social functions with his elegant wife, goes out drinking with his three best friends, and has the occasional, fleeting assignation. Then he meets Maria Fernandez, a dancer at a tango bar in a rough part of town. The beautiful fifteen-year-old intoxicates him. An indigenous dark-skinned Peruvian, she represents everything his safe white world does not, and soon he can’t get her out of his mind. They begin a passionate affair, one that will destroy his marriage and shatter the only reality he’s ever known.    Flash forward twenty years: Against all odds, Carlos and Maria have remained together. But when Maria finally presses for a formal commitment, feelings long suppressed erupt in a tense endgame that sends both of them hurtling toward a dangerous resolution that will forever alter their lives.
