“Put on your sister’s wedding dress—or your mother loses her treatment.” To save her mother, Avery Hart is forced to replace her runaway sister and marry Julian Vale, the disabled heir his own family has cast aside. Everyone believes Julian is broken, penniless, and powerless. Even Avery expects nothing from their unwanted marriage—until she hears footsteps behind his locked study door. Her husband can walk. Worse, he secretly controls a billion-dollar technology empire and is hunting the person who murdered his mother. When Avery’s talent for tracing financial crimes connects her own father to the murder, their marriage becomes more than a contract. Forced to share a bedroom, dangerous secrets, and an attraction neither of them expected, Avery becomes the only person Julian can trust. Then her sister returns. She rejected Julian when she thought he had nothing. Now she wants the billionaire back—but Julian has already chosen his real wife.
