Highland Scoundrel by Lois Greiman

Determined to find a husband for his stubborn daughter, Shona MacGowan's father (Roderic the Rogue and The Flame from Highland Flame) has called to his castle Scotland's most eligible clansman. But for Shona, only one stands out: the stranger, Dugald Kinnaird. His raw, masculine power entices Shona, and when he sweeps her into his embrace, she knows her bow to never marry will soon be broken.

But Dugald's true mission is not to marry the bonnie Scottish lass, but to uncover her as the traitor he believes she is. If playing the suitor will get him what he needs, then he'll pretend to be eager to wed this high-spirited beauty. But as his passion for Shona becomes stronger, this Higland Scoundrel soon realizes he must choose between love...and honor.
