I definitely didn't enjoy this as much as the first book.
This is a sequel, and as such, there is no new mystery. There is very little suspense as well; it's more like an extended epilogue to the first book. It did drag on at times, making me feel that there was nothing new to tell and what I was reading was just stalling.
On the positive side, the time-setting is quite well done, and Dr. Bond's descent into madness is subtle and well-written.
However, the whole romantic triangle with Juliana was, quite frankly, disgusting. That is one trope I hate with a passion, and this one was particularly distasteful. I had already thought, in the first book, that Bond's crush on his friend's daughter was creepy, especially considering how the book ended. In this one, a rival to his affections is introduced, and they proceed to compete for her. Edward is younger, handsome, rich, and presented as a much better option, but I found his attitude towards Juliana enraging: he is forceful, talks over her, tells her how she should feel, ignores her wishes, and stalks her. But, of course, that's exactly what she wants, and turns out she becomes a happy little wife to him. On top of that, we're constantly being treated to detailed descriptions of Edward's arousal at the thought of her, and some sex scenes. I'm not a prude, or adverse to sex scenes, but, really, this book isn't supposed to be smut, and those scenes don't add anything at all to the story. That, combined with his behavior towards Juliana, made my skin crawl.
The treatment of Juliana in this book is deplorable. It's extremely objectifying. She's nothing but a prop in the story, for men to fight over. I understand that the time being portrayed in the text was different, women didn't have much agency back then, blah, blah, blah; that doesn't excuse putting the only female character of the story as the prize to be fought over, the maiden to be protected, and the victim to be abused, and nothing more than those stereotypes. She's never given a voice: almost every character that has any importance to the story gets at least one chapter from their point of view, except for her; Juliana is talked about all the time, but she never gets to say anything for herself.
Overall, I'd stick with the first book and skip this one.
