summary of Her Scandalous Marriage by Leslie LaFoy

The illegitimate daughter of a decadent Lord, the lovely Caroline Dutton has worked hard to become a successful London dressmaker and is content to answer to no man. That is until a devastatingly handsome Duke walks into her shop with the most outrageous demand.

The new Duke of Ryland cursed his fate and his philandering great uncle. To collect his inheritance, he must turn the old Duke’s three by-blow offspring into proper ladies and marry them off. Two are mere children, but Caroline Dutton is all woman – a headstrong beauty he can’t help wanting to seduce.

Now ensconced in Ryland’s country estate, Caroline is being called a Lady and readied for the marriage mart during the next London season. Her dowry is large, her past overlooked, and her prospects bright… except she is breathlessly, madly drawn to the one man who is sweeping her toward scandal – and the sweet satisfaction her heart demands.

excellent review at AAR, and this sounds great…
I have been wanting to try Leslie LaFoy it is great to see her with a new historical! YAY historical! It is a trilogy but hey give it a shot maili ;). Her Wicked Wedding Night is the second title and it wraps up with His Reluctant Bride.
