USA Today bestseller Lenora Bell continues her sparkling, sensual Thunderbolt Club series with a marriage of convenience between a grumpy, combat-scarred duke and his cheerful and beautiful ward.

War hero Deckard Payne, Duke of Warburton, made a battlefield promise to become guardian to orphan Analise Crewe. He certainly didn’t agree to marry the girl! But that’s exactly what happens when he’s forced to wed her to save her honor.   

The last thing Analise wants is a loveless marriage to a brooding—albeit handsome—duke who lives in a gloomy castle and keeps his doors—and his heart—tightly locked. He’s determined to keep her at arm’s length—but she’s not easily deterred when there’s a tough case to crack. 

Warburton never wanted a wife. Especially an inquisitive and far-too-pretty whirlwind who upends his regimented life. Her sunny, winning ways charm everyone she meets and soon she’s unearthing buried secrets, plotting love matches, and shining light into even the darkest of hearts…his own.
