She was a widow with a legacy to protect. He was a rogue with a debt to pay. In the shadows of a mourning veil, a forbidden spark begins to burn.

Adelaide Sterling, the eldest daughter of the formidable Sterling clan, had the perfect life—until the music stopped. After five years of a devoted marriage to Arthur Lowenbrook and the birth of their three cherished children, Arthur’s sudden passing has left Adelaide a widow at the height of her grace. But grief is not her only enemy.

With Arthur gone, the Lowenbrook estate is under siege. Arthur’s avaricious cousin, a man with a cruel streak and a claim to the inheritance, is determined to strip Adelaide of her home and her children’s future. Trapped by the rigid laws of the 1800s and the weight of her black weeds, Adelaide finds herself fighting a war she cannot win alone.

Enter Sebastian Saint Claire. A childhood friend of her brothers and a man with a reputation for silver-tongued charm and dangerous skill, Sebastian has spent years admiring Adelaide from the periphery of her perfect life. Now, he returns to the Sterling fold to stand as her shield against the Lowenbrook vultures.

As they navigate the treacherous waters of the London Season and the quiet, intimate halls of her estate, the lines between friendship and desire begin to blur. Sebastian is determined to save her legacy, but Adelaide is terrified that opening her heart to him means betraying the memory of the man she lost.

In a world of strict propriety and family duty, can a grieving widow find the courage to claim a second chance at love?
