Sophie Ashford and her identical twin Charlotte have spent their lives being compared, confused, and quietly resented by each other. When Charlotte vanishes four days before her arranged wedding to Julian Calloway — heir to a shipping empire and the man their families have spent a decade maneuvering to unite — Sophie steps in to save face, planning to stall just long enough for Charlotte to be found. She tells herself it's temporary. She tells herself Julian won't notice.He notices immediately. Julian has known something was wrong with Charlotte for months — the woman he was engaged to felt like a stranger long before her twin took her place. He doesn't expose Sophie. Instead, he watches her, testing her, drawn to her in a way he never was to her sister, and slowly Sophie realizes he's not trying to catch her in a lie. He's trying to find out why she's telling it and the closer he gets, the harder it becomes to remember which parts of herself she's still pretending.
