I love historical fictions novels and I've always been mildly fascinated by serial killers, so I've been eagerly awaiting this book ever since I first saw it. Overall I thoroughly enjoyed it, though it did have its negatives. 
 pros 
 - The romance was very sweet, and thankfully didn't contain a love triangle. It was of those hate-to-love relationships. It progressed naturally throughout the story and contained playful banter that occasionally made me chuckle. 
 - Though I do really like this genre, sometimes I have difficulties with the way women of this time were treated. I loved Audrey's headstrong attitude combined with her total awareness that she didn't need a man to empower her. 
 - The pacing was excellent, I never really got bored. The writing was awesome as well, and the pictures at the beginnings of some of the chapters were the perfect touch. 
 - I have this bad habit of flipping to the back of a book I'm reading to see how it turns out, so I knew who Jack was before even starting the novel. Because of this, some of the tension was lost on me but if I hadn't spoiled myself, I think I would have really appreciated the way the mystery was crafted. 
 Cons 
 - The way Audrey behaved towards the climax of the book kind of baffled and annoyed me. (view spoiler)[When she went down to the laboratory in her house without first going to get help, she was obviously going to run into the killer down there. (hide spoiler)] 
 - I thought the ending was really rushed. Like the main event occurred within a chapter and the aftermath felt a little too neatly tied together. (view spoiler)[Aubrey solves the mystery of Jack the Ripper, gets together with Thomas and soon afterwards her father suddenly agrees to send her to medical school despite being totally against it her whole life? Especially after just witnessing what similar fascinations with death did to his son? It just felt it was done for the sake of getting a happy ending, not because it was realistic. (hide spoiler)] 
 - I think this would be better off as a standalone, I have no idea what the sequel will be about. (view spoiler)[After all, Jack the Ripper (aka Nathaniel) was quite obviously dead (hide spoiler)]
