Mr. Dale and the Divorcée - The Brazen Beauties, #1

He's a respectable barrister... She's the most scandalous woman in England... Wilhelmina Hewitt knows she's in for a rough ride when she agrees to help her husband get a divorce. Nothing, however, prepares her for the regret of meeting Mr. Dale on the eve of her downfall. No other man has ever sent her heart racing as he does. Unfortunately, while she'll soon be free to engage in a new relationship, no upstanding gentleman will have her.
James Dale would never pursue another man's wife. Or a woman reputed to be a deceitful adulteress. Furious with himself for letting the lovely Mrs. Hewitt charm him, he strives to keep his distance. But when her daughter elopes with his son, they're forced into a partnership where passion ignites. And James soon wonders if there might be more to the divorcée than meets the eye.
