Archaeologist Dr. Gwen Finnegan is on the hunt for her lover’s killer. Historical researcher Justin Yates bumps into her, literally, on the steps of the New York Public Library, and comes to her aid when she’s attacked, sparking an attraction between them in spite of their age difference. After avoiding a cadre of pursuers at the Met Museum, Gwen impulsively invites Justin to hop a plane with her to the UK. The shy historian, frustrated with his failing relationship, jumps at the chance to join her on a real adventure. That adventure takes them through Europe, pursued by factions including Gwen’s ex-lover and nemesis, Karl, as they try to unspool fact from fiction in a multi-generational obsession with a statue of the goddess Medusa.
