Already deeply in debt, George Upperton learns that his mistress is with child and she and her aggressive brother want him to pay her a hefty compensation. George flees with his family to his newlywed friend Revelstoke's house party where he hopes to get a loan or hustle the other guests for blunt. Out for a stroll on the beach, George encounters a barefoot Isabelle Mears and her little boy, Jack.

Isabelle was ruined by a gentleman like George and has fallen out of good society. Thus she will have nothing to do with a man like him or any man for that matter. Isabelle and her son hide away from the world in a small cottage on the outskirts of the village near Revelstoke's manor.

When Jack is kidnapped by men unknown, Isabelle and George join forces to get him back.

A MOST DEVILISH ROGUE by Ashlyn Macnamara is a historical romance set in regency England. A MOST DEVILISH ROGUE is the sequel to A MOST SCANDALOUS PROPOSAL. Macnamara's descriptions are eloquent and flowery, sometimes they are a bit over the top though. Isabelle is a little bit too stereotypical in her "jilted maiden against the world" type. George on the other hand is refreshing. While he is the typical flawed with serious problems hero he isn't all dark, stoic, and broody. George is witty, his defense mechanisms cause him to make light of everything, hiding what he really feels. Jack is a fun addition to the story and he is the catalyst of most of Isabelle and George's interactions. I will say that there seem to be a lot of obvious puns in the last names of the characters.

A MOST DEVILISH ROGUE starts off as a fun and decent historical romance and in the sea of historical romances I wasn't sure I'd pick up another Ashlyn Macnamara. But the writing definitely improves as the story goes on. I found myself quickly flipping to the next chapter at each chapter's end. A MOST DEVILISH ROGUE is a worthwhile read.
