Highland Beast (Sons of Sinclair, #04)

Bàs Sinclair is the cold and brutal hand—and sword—of justice across the Highlands. He has one destiny: to bring fear into the hearts of guilty men. But when he is called to execute a midwife for her crimes, he cannot raise his weapon. For Bàs already knows this lovely, part-wild creature. After all, she gave him his first and only kiss…
Shana Drummond will do anything to protect her beloved sister. Now her cruel, merciless brother-in-law has called upon Bàs to have Shana killed for crimes she didn’t commit. She can’t reconcile the cold, lethal warrior before her with the gentle one she met—nay, kissed—only days before.
