Prince of Ravenscar — Catherine Coulter

In April 1831, her grace Corinne Monroe wants her widowed son, Lord Julian, to marry her best friend's daughter, Miss Sophie Wilkie. Julian last saw Sophie when she was twelve years old, silent, skinny, and always staring at him. However, his mother is nothing if not persuasive, and Julian reluctantly accompanies her to London to meet the young lady.

And he knows that whatever happens isn't going to be good.

Lord Devlin Monroe, Julian's nephew, is very fond of his intriguing reputation in society: he delights, he frightens, he brings on delicious shudders. He's enjoying an extraordinarily pleasant bachelor life until Miss Roxanne Radcliffe and her niece, Miss Sophie Wilkie, appear in London society, and he finds himself wondering how he could have enjoyed midnight alone.

Julian and Devlin must discover what really happened three years earlier when Julian's first wife, Lily, was found dead. If they don't find out the truth, their lives could be ruined. And there is another, even more perfidious, danger that lurks in the shadows, waiting.
