I'm very divided on this book. It's not a Regency-era book. It's late-Georgian. There's only one reference to the period at the very end.
This is not a happy, fluffy romance. It's not dark, but it is a mystery with conspiracies, political intrigue and a few deaths. That doesn't necessarily make it bad. There were some editing issues, but not many. I did not like the three, yes, three sex scenes. They really had plenty of time to get married. He had the special license in his pocket for a while, they just chose to never get around to it. Even the hero considered their time together a 'lapse in judgment.'
I don't know if it was all the sex, the writing style or the non-fluffiness of it all, but I couldn't love this book. I only finished it to discover who the murderer was.
I liked the 'voices' she heard and that whole aspect, although it was hard to follow at times. I loved that there was an epilogue. Too few books have them. Very nicely wrapped up.
Not horrible, but could've been a lot better.
