'[E]ffervescent... Sophie is a refreshingly candid protagonist, whose ability to stand up to the duke is evenly matched with the care and concern she has for her sisters. Waters's fans will be sad to see this series end but deeply satisfied by this fetching finale' Publishers Weekly

The final instalment in the "hilarious and steamy" (PopSugar) Regency Vows series follows the heir to a dukedom and a young widow, once very much in love, as they reunite years later to fake an engagement for the benefit of her sister.

They have the best of intentions...and the worst luck in love.

West, the Marquess of Weston, and Sophie, Lady Fitzwilliam Bridewell, have lately been spending a considerable amount of time together. But West and Sophie are not new acquaintances.

In fact, years ago, they were almost engaged, until West's almost fatal curricle accident and his meddling father threw them off course.

Now, having recently lost her husband, Sophie has put aside all thoughts of romance. But when her widowed sister, Alexandra, mentions a fondness for an earl, Sophie realises she may be holding her sister back. Alexandra won't move forward until Sophie, too, settles down again, and so Sophie approaches West with a plan. They will announce their engagement and break things off once Alexandra is happily married.
