Petite, fierce, and respected by the men who work for her, Daisy Connelly rules her rare watermelon tourmaline mine in Newry, Maine, with an iron will. When profits begin to vanish and the local sheriff refuses to intervene, Daisy realizes someone is stealing from her-and that remaining an unmarried woman may make her an easy target. So she does the unthinkable. Daisy proposes a marriage of convenience to private investigator Samson Gray, hoping a sudden husband will draw the culprit into the open.

Samson has built his reputation on solving dangerous cases, not playing the role of a devoted spouse, but Daisy's audacious plan may be the only way to catch a thief who believes himself untouchable. What begins as a calculated ruse soon grows dangerously complicated.

As threats tighten around the mine and trust becomes a fragile gamble, Daisy and Samson are forced to confront old wounds, buried fears, and the walls they've built around their hearts. Pretend vows blur into genuine emotion, and the cost of independence-and love-rises with every step closer to the truth. Because when deception turns deadly, faith may be the only thing strong enough to save them.

Set against the rugged beauty of Maine's gemstone country, this Christian historical romance weaves heart-pounding suspense with a tender romance and faith forged under pressure-where the greatest treasure isn't found underground, but in the courage to trust, surrender, and love.
