Don't Mess With My Duke Dubless!

Duke Dubless has been scorned by all who meet him: the villainess, the protagonist, even the author of his story. But when a woman from the real world transmigrates into the novel as the duke's sworn knight, she swears to protect her favorite character from any and all threats be they physical or emotional. Can Jane make good on her knightly duties and protect her fave from attacks on all sides? (Source: Tapas)
