A chance meeting on the New York subway leads to the destinies of two very different women becoming intertwined with terrifying consequences.

Sixteen-year-old Addison is on the run. She's leaving her life on New York's streets behind for a new one with Rafe, armed with just his phone number on a scrap of paper. She's taking the subway to meet him in New Jersey. He'll take care of her. Or so she thinks . . .

Elizabeth Brown's world has fallen apart and she's thinking about her newly ex-fiancé. Until she locks eyes with a teenage girl while waiting for the train doors to open, and a bundle is thrust into her arms as she leaves the subway. A baby, wrapped in a dirty coat.

Elizabeth phones the number she finds in the coat pocket. Then wishes she hadn't. Someone wants Addison and the baby. And they'll do whatever it takes to get them . . .
