I was a little dubious about reading "One Wicked Sin" after finding out the heroine was Lottie Cummings. She was in the previous book in the series as a secondary character and I didn't like her at all.
However, although I found it difficult at first to forget how awfully she had treated her best friend by sleeping with her husband, trying to seduce her new husband and betraying her in other ways, I did begin to like her more and more as I read each chapter. I began to understand why she was the woman she had become, but I still think it was daring of the author to think that all would be forgiven and forgotten.
We find Lottie in a poor state of affairs after her husband had divorced her due to her indescreet affairs. Without the support of her family and her only true friend out of the country, Lottie didn't have anyone to turn too. With no money and no place to live, the only option she could see was to turn to prostitution. She hates it with a passion and has lost all her confidence. She is now a broken woman and competely different from the one we met in 'Whisper of Scandal'.
One evening a gentleman offers to pay her to be his mistress, and upon reflection Lottie felt that this was the lesser of two evils, so she agrees. She did not expect to fall in love.
Ethan Ryder is a great hero - at first he uses her, but not in a rough way. He's gentle and caring, but he still sees her as something he has bought. But after only a few days he begins to have feelings for her that confuse him as he's never felt anything like it before. Ethan grows considerably throughout the book, as does Lottie and they find true love.
The one aspect that prevents "One Wicked Sin" from a higher rating is the balance of sex and plot. With 'Whiper of Scandal' Cornick gets the balance perfectly, but here there is too much talking and thinking about sex. If they're not thinking about it, they're talking about it and if they're not talking about it they're doing it. And although I realise that sex, lust etc is part of a romance novel, there is too much of it here for my taste and nothing much else happens for a good portion of the novel. However, the second half is much better balanced that the first.
Overall, "One Wicked Sin" is a fun, entertaining read and the characters growth is touching and heartwarming. Cornick gives us another romantic ending that makes the heart flutter.
