The last of the Hellions of Havisham is the hero of The Viscount and the Vixen by Lorraine Heath.
Actually, I wouldn’t exactly call Portia, the heroine, a vixen. When I think of that term, I think of an overly flirtatious young miss. Portia is way too knowledgeable and overtly provocative to qualify as merely a vixen.
She also is hiding a whopper of a secret. She arrives to marry Locke’s father, some decades her senior. Locke decides to protect his father and marries her himself. After all, he does need an heir, but he has no intention of loving anyone as much as his father loved his late mother. Her loss only led his father to madness. There’s no chance Locke will fall in love with this little gold digger.
But apparently dear old dad wasn’t so crazy after all. He engineered the whole thing, somehow knowing the two would be ideal for each other.
This book is rather racy for me, but the pair are hard-working, kind, and most importantly forgiving.
