This author has earned a well-deserved place on my DNR list.
This book is well-written in terms of spelling and grammar but I've rarely seen a more miserable bunch of characters.* Even in books with numerous unpleasant characters, the hero reforms and/or the heroine learns the error of her ways. In this book she learns to tie the right knots for S&M.
I don't believe it's a spoiler to say that, in addition to sex for money and sex for revenge, and near rape, the main characters indulge in a little S&M, heterosexual incest (a female child seduces her father), homosexual incest (sisters) and even a character who couldn't get it up. Thank goodness there were no sheep in the book!
*OK, not counting any books in which the heroine kills her sex partners or books where characters eat each other.
