One thing I would like to make clear about this book is that it is nothing like Rebecca which is one of my all time favorite novels. With that being said, this story was an okay read. I found the supernatural element mixed in with a bit of mystery to be great. Imogen as a MC was likeable. She showed real spunk and level-headedness throughout. Her romance with Sebastian was a tad bit cliche with it all being insta-romance (I do not qualify a 10 year old having feelings as the makings of a great love story especially as there isn't any follow up afterwards except when she comes back to the Manor). The worldbuilding although not stellar was at least existent and we catch a glimpse of the opulence that is Rockford Manor. I liked how the book shows Imogen navigating the British peerage and coming to term with her life as an heiress. 
 However, this book did have its faults. The ending was deporable. One of the worst I have come across. After all the build up, it just falls flat. I also would have liked to see more of the side characters' stories. We get heavy doses of Imogen but the others seem to just fade in and out of her life. I needed to see more of her relationships and more backstory. Other than that, I did find the novel reasonably enjoyable. It's good for a one time read. I think if you try to compare it to Rebecca you would be majorly disappointed. So, I would suggest putting it out of your mind and reading it as a whole new and different story.
