Disgraced eldest sister Claire Summers has been living in exile as companion to a stern great-aunt in Scotland. About to become homeless and longing to be reconciled with her estranged family, Claire answers an advertisement from someone looking for a "respectable female partner" in a Sidmouth boarding house. Is it a sign or another reckless mistake? When she meets the handsome, secretive proprietor, she wonders what he's hiding and if he's any more trustworthy than the nobleman who betrayed her years ago. Even as she is drawn to him, she fears he will reject her when he discovers her genteel façade hides a less-than-respectable past.

Meanwhile, the Summers family learn their great-aunt has died and Claire has disappeared without a word. The sisters rally together to find their lost sibling, but will their unexpected reunion heal old wounds and rekindle their bonds . . . or widen the divide?

Return to the picturesque Devonshire coast as the Summers sisters navigate romance, second chances, and the enduring strength of sisterhood in the face of adversity.
