Private Investigator Carlotta Carlyle is awakened by a late-night phone call telling her that Paolina is missing. Fourteen-year-old Paolina was paired with Carlotta by a mentoring program in Boston years ago, and she knows that Carolotta loves her like a daughter. As Carlotta combs the streets of Boston, then Miami, then Bogota in search of Paolina, she thins of another child; the baby she gave up for adoption when she was fifteen. Tense, emotional, and frightening, Heart of the World follows Carlotta as she searches for Paolina. When she's kidnapped by Paolina's notorious father, the outcome is that this very unlikely pair teams up to find the missing teenager. But first they must know -- was Paolina kidnapped, or did she run away?
