The Duke's Covert Mission by Julie Miller
Dispossessed Duke Cadence St. John might be a maverick mercenary. He might have sold his soul to the highest bidder, but he wouldn't hurt shy, bespectacled royal secretary Ellie Standish--had he recognized her that is! She had transformed herself into a stunning beauty for the Inferno Ball, a metamorphosis so complete that, instead of the real princess, his cohorts had kidnapped the wrong woman! Held in the dark confines of a remote cabin, Ellie would be killed if her identity were discovered. Cade vowed to stay near and protect her with his life. But when the heated sensuality of their forced proximity became too much, would Cade be able to complete his mission with not only his life, but also his heart, intact?
