Park Square. Mass Ave. The Combat Zone. All home to Boston's sex trade. Home also to runaways and lost souls, home to high rollers and politicians looking for action they can't find anywhere else. It is home, too, for Father Clancy Donovan, who spends his time here trying to get young girls off the street. Bone weary and frustrated, he has lost the joy in his life and has no idea how to get it back.

Divorced three times and not yet thirty-five, Sarah Connolly is trying hard to make a new start when life throws her a curve. Kit, her fifteen-year-old niece, has run away from home, and Sarah will need every ounce of her stubbornness and determination to track her down. Suspecting Kit has disappeared into the Combat Zone, and with no one else to turn to, Sarah appeals to Clancy for help.

The unlikely pair team up to find Kit, but in the process find something else - something powerful, something unexpected and something that will shake them to their core.
