Patience Carruthers is a bluestocking with no interest in the fleeting uncertainty of love. Her passion is for books, knowledge, and the improvement of the world. When she learns of Mrs. Oliver's work, instructing ladies in intimate matters to better their marriages, she is resolved to see that volume published for the public good—and will even accept an agreement to wed a notorious rake to accomplish her goal.

Thanks to his uncle's reckless wager, Arthur Beckham has immediate need of a wife. Insisting he has an understanding with Miss Carruthers, a lady of good sense and practicality, may provide an escape from his predicament—assuming the lady in question can be persuaded to agree. He proposes a marriage of convenience to Miss Carruthers, vowing he will do whatever she desires in exchange for one son—even ensure the publication of such an uncommon volume.

Arthur is intrigued by this lady and her ability to surprise him. Her commitment to honesty tempts him to abandon the disguise that has defined his life for decades—though Arthur fears that admitting his deception might turn Patience against him forever. Can the book help him to capture the heart of his pragmatic bride before his secret is revealed?
