Return to Wildsyde by Emma V Leech

Their mothers dared all for love…
Their sisters did the same.
Something wicked this way comes…
The oldest trick in the book…
When Lyall Anderson, Viscount Buchanan, starts a passionate affair with Miss Lilith Fulbright, he realises too late that he’s been playing with fire. Caught in a compromising position by her parents, it’s all too obvious the beautiful, amoral young woman is only hungry for wealth and a title and has no regard for him whatsoever. Humiliated and furious, Lyall does his duty as an honourable man, knowing that his future with such a woman will be one of misery.
