Derrick “Leo” Armstrong built Serenity Securities as a refuge—an unbreakable brotherhood forged from military scars and second chances. On Serenity Mountain, he finally found the life he’d always dreamed of: a home, a purpose, and Catherine, the woman he’d loved for a lifetime. With three children and another on the way, Leo believed his world was complete.

Then one mission shattered everything.

Left reeling by the devastating news of her husband’s death, Catherine must navigate grief while protecting the family Leo adored. As the men of Serenity Securities rally to bring their fallen brother home, the mountain community surrounds Catherine with the same fierce loyalty Leo once gave them. But when a final letter from Leo forces her to face an impossible truth, Catherine makes the heartbreaking choice to call off the search. Her children need closure. Life must move forward.

Leo’s team refuses to accept it.

Driven by loyalty, love, and the lessons Leo carved into their souls, the men of Serenity Securities push deeper into danger, determined to uncover the truth about their mission and bring their brother home. Their greatest mission isn’t one they were trained for. It’s one they learned from Leo himself:

Family is worth fighting for.
