He ruined her sister's life. Now she'll make him regret it.

Elspeth Macquarrie's brother vanished while seeking an alliance with the Maxton clan at the Scottish borders. While everyone else believes he's dead, she refuses to lose hope and is determined to find him. When an unexpected marriage proposal arrives from Logan Maxton, Elspeth sees a chance to uncover the truth.

But Logan is the man who shattered her sister's heart two years ago by ending their betrothal with nothing but a letter. Fueled by anger, Elspeth agrees to marry him, planning to abandon him just as he did her sister.

Yet, Logan is one step ahead. He offers a daring deal: he'll reveal what happened to her brother if she agrees to break their betrothal herself. Caught in a web of secrets and revenge, Elspeth must decide—can she trust the man she despises, or will she meet the same fate as her brother?

The stakes are high, and the heart can't be trusted. Will Elspeth find her brother, or will Logan be her ultimate downfall?
