Not Fit for A King? (Harlequin comics)

No matter how much we look alike, the prince will never love me. Hannah, an American secretary, agrees to switch places with Princess Emmeline, just for two hours. There must be a reason that made her ask me for such a favor. Besides, it’s only for a few hours. But Emmeline doesn’t return for days, and Hannah ends up having to meet King Zale of Raguva, pretending to be the princess!
