Isabelle by Carrie Lomax

Isabelle Kingston risked everything for a kiss. Now the most beautiful debutante in London is set to marry England’s most reluctant groom.

It is not true that a single man in possession of a good fortune must be in want of a wife. Lord Silas Huntley was perfectly content with his bachelor lifestyle, until Miss Isabelle Kingston ruined it.
Why would the diamond of the Season, a lady who had her pick of London’s eligible men, entrap him with a stolen kiss? And the bigger question is, what will he do with her now that they’re married?
But by the time he figures out what it is he wants – Isabelle, in his bed – Silas’ indifference has damaged her fragile confidence. Can he win back the love she gave so easily, or is his once-unwanted wife gone for good?
