Eight-year-old Emma is hiding in a closet while her mother’s violent boyfriend searches the house for her. Desperate and unable to call for help, she sends a text—but enters one digit wrong. The message reaches Matteo Ricci, the most feared crime boss in Boston. Matteo should ignore it. Instead, Emma’s words awaken a promise he buried twenty-five years ago. As he races through the rain toward a family he has never met, he must decide whether the power he built through fear can finally be used to protect someone innocent.
