Returning to the rugged Highlands, Barclay MacFarland faces a shocking betrayal—his own step-uncle is seizing his birthright. Desperate to reclaim what's rightfully his, Barclay turns to his childhood friends at Braenaird Castle. Amidst the enchanting Douglass sisters, it's the quiet and unassuming Aileen who offers a daring solution: a marriage of convenience that could outwit his uncle without a single battle.

Agreeing to the plan, Barclay proposes to Aileen, who never imagined herself a bride. Overshadowed by her vivacious sisters, she's resigned herself to a life alone. But as their union unfolds, Aileen's heart yearns for more than just an agreement. Yet, Barclay remains distant, viewing their marriage as mere strategy.

As danger looms and enemies close in, Barclay's survival may hinge on the one woman he's keeping at arm's length. Will Aileen have the courage to fight for a love that seems unreciprocated? Can a cold alliance ignite into a passionate flame before it's too late?
