Gabriel Angelstone (also known as Brimstone) is a rake. He loves women and women love him. However, he doesn't believe in love per se, he goes through life enjoying women on a "casual" basis.
Showing up early to a party being hosted by his close female friend George and her husband Ivo (the main couple in the author's previous book Lord Sin), he initially mistakens Imogen for George. Imagine his surprise when he discovers that it isn't George but a mysterious woman who's witty, well-read, and of course, beautiful. He's immediately attracted to her and can't resist making a pass at her. Imogen finds Gabriel attractive, but the last thing she needs is any notoriety, as she is trying to recover from being outcast from society.
Imogen is a divorcee. Her husband divorced her after a shocking portrait of her was painted. Since that time, life has been hard for Imogen. She's been cast off by her family (and a brother who hates her) and prior to meeting George, was living in a boardinghouse.
What follows is the romance of Gabriel who finds that yes, he now does believe in love and Imogen, torn between Gabriel and the hope of getting back into society - something that can't happen if she's with Gabriel.
If you read Lord Sin, you'll find that there are some familiar characters back in this book (like the heroine, George) and lots of secondary characters. Timing-wise, this book takes place after the main story of Lord Sin, but before the epilogue in that book.
I read and enjoyed Lord Sin and was curious to see how the author did with a second novel. I actually think I enjoyed this book more than Lord Sin. One of the issues that I had with Lord Sin was the lack of dialog in some key scenes. No such problem here, it seems like the author has done a great job with dialog. All in all, I enjoyed reading about Gabriel falling in love and Imogen unable to resist Gabriel.
