Heart of the World

When private investigator Carlotta Carlyle is wakened by a late-night phone call, she discovers that her “little sister,” Paolina, the child with whom she was paired years ago by a local mentoring program, is missing. Carlotta combs the Boston streets looking for Paolina, torn between anger at the thoughtless teenage runaway and anxiety that something has really happened to her. Paolina is more than a sister to Carlotta. She's the daughter she never had, or never owned up to having. She's the one constant in Carlotta's life, more reliable than Sam Gianelli, her mob boss lover, a man whose always unpredictable behavior has become increasingly mysterious.
