When Marcy Jensen gave her father her word, she didn't realize it would bind her to a impossible choice. Those two simple words—"I promise"—became the chains holding her to sanity itself, the only lifeline to memories of who her dad used to be before everything fell apart. Breaking promises isn't in Marcy's nature. Not when her brother's future depends on it. Not when it's the sole reason she drags herself forward each day. Not even when that vow forces her into servitude as a 24-year-old maid for the most ruthless man in existence. Some promises are sacred. Others are cages. This one might be both. Her only way out? Taming Mr. Robinson—a billionaire whose cold heart seems as impenetrable as the contract that binds them together. But as the line between duty and desire blurs, Marcy discovers that some promises are worth breaking, and some prisons are worth escaping.
