The Arrow (Highland Guard #9)

As King Robert the Bruce of Scotland plots to retake his English occupied castles, he needs the stealth and skill of his elite soldiers, the Highland Guard. Fearless and indomitable, no men are more loyal to their king, or cherished by the women they love.
 
The talents of legendary marksman Gregor “Arrow” MacGregor are crucial now, as Bruce moves to reclaim his Scottish holdings. Gregor is considered the most handsome man in Scotland, and his fame as an archer is rivaled only by his reputation with the lasses as a heartbreaker. But when his infamous face is exposed during a covert mission, Gregor is forced to lay low. He returns home only to find a new battle waiting: a daring game of seduction involving his now very grown up and very desirable ward, Cate of Lochmaben.
 
A born fighter, Cate was clinging to life when Gregor rescued her after a vicious English raid on her village left her mother dead. But five years later, the once scrappy orphan Gregor took under his protection has become a woman. Brave, strong, and skilled in warfare, Cate is determined to lay claim to the warrior who refuses to be trapped. The heat in his eyes tells her she has his attention . . . and his desire. But will Gregor allow his heart to surrender before danger finds them, and the truth of Cate’s identity is revealed? Rated '4/5 - Explicit open door' for steam/spice/heat level.
