An undercover warrior and her sworn enemy play a seductive game of cat-and-mouse in New York Times bestselling author Monica McCarty’s sexy new Highland Guard novel.

Joan Comyn swore allegiance to Robert the Bruce the day she witnessed England’s barbarous king torturing her famous mother, Scot patriot Bella MacDuff. Now the mysterious beauty slips into men’s hearts like a specter and entices England’s most illustrious barons to unwittingly divulge their secrets, then shares them with her king. Known only as the Ghost even among her Highland Guard brethren, Joan has become the most wanted traitor in England.

The man determined to uncover her identity poses her biggest threat yet. Alex Seton once stood with Bruce but now fights for the enemy. Though Joan knows she must avoid the handsome warrior or risk discovery, his knightly chivalry touches a place in her long since buried. When his suspicions grow apparent, Joan realizes she must do everything in her power to stop Alex from revealing her mission and convince the powerful fighter to join forces with the Highland Guard once more. But as the ultimate battle in the great war approaches, will Alex choose love or honor?
