Sienna Vance was never meant to be seen.A structural engineering prodigy with an instinct for markets and systems, she spent years building a future that bore another man’s name. Her husband, Julian Vance, rose through Chicago’s architectural elite on designs he did not create, while slowly erasing the woman who made his success possible. When Sienna discovers Julian’s betrayal—an affair with her own stepsister and a premeditated divorce designed to strip her of everything—she disappears overnight. The world is told she has entered rehabilitation. In reality, she has been traded. To settle a family debt that could destroy their last shred of social standing, Sienna’s parents deliver her into an arranged marriage with Kris Blackwood: a reclusive billionaire known for his ruthless acquisitions and merciless reputation. Publicly, Kris is cold, distant, and confined to a wheelchair. Privately, he is something far more dangerous.
