This author's name has cropped up a few times on amazon.com discussion boards, and I was intrigued enough to track down this book, which was on offer at my library, and a good find it was too.
It's a historical erotic romance, where nice-girl-who-would-be-bad-given-a-chance, Venetia, is trying to protect her family's rather dismal fortunes by preventing an ageing courtesan from blackmailing her father. She is illegitimate, but cares for him and seems to have to mother him, and when he becomes unable through ill-health to continue with his books of erotic illustrations, she takes over, drawing the pictures and telling the stories, from which she achieves vicarious thrills. Yet no-one is allowed to know of her scandalous 'job' or she and her sisters will be ruined.
Strangely, her father's male subject in most of his works appears to be an earl called Marcus, who has become both famous and infamous due to the way in which he is depicted, but Marcus is the one who will help her attempt to gain access to the blackmailer, at, of all places, a country estate where the ton has gathered for a week of debauchery and orgies. Right?
Anyway, Marcus is a gentleman in his own way, so refuses to allow to go alone, and refuses to sully her by taking her virginity, but he is willing to introduce her to all of the other pleasures of the flesh, whilst hiding from her that his reason for taking her to the orgy is that he is also being blackmailed. Venetia is a delight of a female lead - assertive, knowing what she wants, a virgin but not a prude, and rather emancipated.
Yes, the book takes us through a succession of orgies and depraved acts, with males and females, married and single participating equally, and yes, it becomes a whodunnit, when the courtesan is murdered, though neither her diary/manuscript nor her book of names is found, and pretty much everyone is a suspect. That is, in between bouts of copious sex. You name it, it was taking place, and virginal Venetia took to voyeurism and mild exhibitionism like a pro!
A really good romp of a tale, with likeable leads who were clearly more than just physically attracted to each other from the very start. I've since bought two more of her novels, and the theme of them seems to be a virginal female lead, a bad boy male lead who's matured into a decent person, the introduction of various sex acts, including light F/F with toys of all sorts, to the female lead, who takes to all like a duck to water. Yet, there's no 'real sharing',(other than in her committed, permanent M/F/M menage books),just experimentation before a HEA.
