Twenty-four hours. Half a million dollars. Or his mother dies. Omega Caelen Ryn is out of options: his mother is dying, treatment costs half a million dollars, and loan sharks are closing in with brass knuckles and threats. Then a lawyer appears with an offer from Alpha billionaire CEO Aldric Fenmore: marry him for two years, every debt disappears, and his mother will be saved.

Behind closed doors, they're strangers. Until Monaco. When Aldric's race car spins out at 200 mph, Caelen realizes the truth-he's fallen in love with his husband. And when Aldric kisses him after his victory, raw and desperate and real, the contract between them shatters completely. They broke every rule. They fell impossibly in love.

Or the child they never planned for. In that impossible moment, every vow they made, every sacrifice they offered, and every fragile dream they built together came down to a single, devastating choice. A contract that was supposed to end. A love that refused to.
