Some debts aren't paid in money. Lydia Voss signs the contract to save her family. One year. One marriage. One man who already knows everything about her. Xavier Knight didn't just clear her family's debt. He's been waiting for her. Inside his glass mansion, nothing is what it seems — not the walls, not the contract, and not the man who watches her like she's the only thing in the world worth owning. The longer she stays, the more she realizes the cage was built long before she arrived. And the most terrifying part? She's starting to want the key.
