Mavon returns to her ancestral home, with her young daughter, in order to attend the funeral of her grandmother. It was supposed to be a quick trip and she would return to her life in the city. Of course, even the best laid plans go awry when witch craft is involved and her grandmother’s body goes missing.

 To add insult to injury, it was inevitable that she would run into her arch enemy Ronan Croft.  Ronan is the billionaire heir and current CEO of Croft Pharmaceuticals. However, they were not always enemies. They had been lovers and even if Mavon wants to forget, her body has not. With each encounter more of their past is revealed and some secrets are not going to remain in the dark.

I love books that are character driven. It is the main thing that drives my quest for great stories. However, this book was all about the multi-layered plot and witty, cutting, banter. Yes, the characters were great; however, I got so wrapped up in the plot I didn’t pay as much attention as I normally do to character develop. In fact, I got so invested in this story that it had me reading until 2:00AM to finish.

The chemistry between the MMC and FMC was off the charts and I liked how the author built up the tension. Both characters had a lot of past baggage they each had to unpack and there were a couple of questions I had that were not answered until the very end. The book definitely had my complete attention the entire time I was reading.

The plot was fast based and there were plenty of twists. A couple of big twists actually. There was one twist at the end I figured out, and you will too if you pay addition to the details. I liked that the author allowed me to figure it out. It was as if she was seeing how clever her readers could be.  

This is a dark romance; so, read the warnings carefully. That said, this is on the lighter side of dark romance. If dark romance can have a light side.  In addition, this book has a lot of the same vibes as PenPal. Therefore, if you read and enjoyed that book you need to read this one NOW. For those readers who have not read any books by Geissenger, you need to read this book if you are into dark romance.  In summary, an enjoyable read and I highly recommend.

I received a free copy from the publisher, via NetGalley, in exchange for my honest review.
