It was a command performance

Chantal Giraudeau de Montcroix was every inch a princess, and she expected the red-carpet treatment during her American tour to promote a traveling art exhibit. What she didn't expect--and wouldn't tolerate--was special agent Caine O'Bannion hounding her every move and cramping her formidable style.

Caine had this crazy notion that someone was out to kill her, and his constant surveillance was becoming a royal pain for Chantal--until the first attempt on her life. It was then that she commanded he keep watch over her... day and night.
