Mairi Cameron has been haunted by a dark secret that drove her into a convent at fifteen. Years later, a letter from her father summons her back home to marry. Conflicted and uncertain, Mairi's life takes an unexpected turn when Hugh Monteith, a dashing Scottish sailor, arrives at the nunnery in need of aid.

Drawn to his kindness and captivated by his charm, Mairi proposes a daring plan: marry Hugh to avoid an arranged marriage with a stranger. As their connection deepens, love blossoms—but a shadow looms over their happiness. Hugh's brother died years ago, and Mairi knows more about that tragic day than she can admit.

With her past returning to haunt her and the truth threatening to tear them apart, Mairi must decide: will she risk everything to protect her secret, or will she find the courage to face the consequences and fight for the love she never expected?
