She signed for love. He signed for revenge. When billionaire tycoon Jonathan James dies, his final will detonates a bomb no one saw coming: he leaves his entire empire not to his only son Andrew, but to the family's longtime butler. The one condition? Andrew can reclaim the company - if he marries Julia Matthew, the butler's daughter and Andrew's childhood best friend. Blindsided and furious, Andrew proposes a cold, calculated deal; a fake marriage to Julia to meet the will's terms and take back what's his. Heartbroken but loyal, Julia agrees - concealing feelings she kept hidden for years. But as they live under the same roof, the walls between them begin to crack, passion reignites, old wounds resurface, and buried secrets threatens to destroy everything. In a world where power, pride and legacy collide, a love might be the most dangerous clause of all. The Marriage Clause is a slow-burn, enemies-to-lovers romance filled with betrayal, longing and the kind of tension that makes heart race and pages turn.
