The secret princess's bodyguard... As head of a visiting royal's protection detail, Trace McKinnon's focus should be strictly on the external threats against a woman's life. But what happens when he finds Dr. Mara Marianescu--a princess incognito as a college professor--much more intriguing? And that's only the start of his troubles. When actual danger arrives for this beautiful royal, Trace isn't sure if it's because of a genuine threat from her country--or because of the darkness in his own past. Trace knows he should let Mara go--and does his best. But the cool, intelligent princess might just risk the one thing she has that is all her own--her heart...
