Genevieve has secrets that no one knows. In Rome she can be whoever she wants to be. Her neighbours aren't nosy; her Italian is passable; the shopkeepers and restaurant owners now see her as a local, and they let her be. It's exactly what she wants. One morning, after getting groceries, she returns to her 500-year-old Trastevere apartment - it's exactly as she left it, not a thing out of place...except for the small box on her kitchen table. A box that definitely wasn't there this morning. A box that is addressed to "Lucy Callahan." A name that she hasn't used in 10 years.
