The Sinclair Hound by Caroline Lee

Decades ago, the legendary jewels in the Sinclair brooch went missing. Now it's up to a new generation of Jewels to restore the clan’s fabled talisman…and with it, their family’s power! Known only as the Sinclair Hound, the scarred and silent warrior owes his loyalty to the laird who saved him from hanging as a lad. Now he is content to spend his life protecting his adoptive clan and his master’s family.... until one of the laird’s daughters challenges that devotion and forces the Hound to make a fateful choice. As the youngest of the Sinclair Jewels, Lady Pearl has made a place for herself among her clan, serving her people and doing her best to care for those who need help. Unlike her sisters, she has no interest in leaving her family. But when she’s forced to choose between an unwanted marriage or taking holy vows, she makes a fateful mistake. If she can’t stay with her clan, she’ll become a nun. But once her sire tasks the Hound to escort her to the abbey, Pearl is forced to admit two things: she never really wanted to take holy vows and she can no longer deny her fascination with her bodyguard. Even if he doesn’t speak, his lips have other ways of intriguing her! But the Jewels have enemies, and when danger closes in, her father’s Hound is the only one who can protect her. As love becomes the greatest treasure of all, can they find a way to stay together, or will violence and family secrets keep them apart forever? Warning: Scorching hot Highlander romance! Meet the Sinclair Jewels, four sisters determined to restore their clan's power: Sweet Pearl, thoughtful Agata, scholarly Sapphire, and fiery Citrine! Each will journey across the Highlands to find love, and together they'll solve a decades-old mystery! (This book is a re-release of a 2019 book with the same title.)
