I loved this book! It was a lot better than I thought it would be. The characters were amazing especially the main character Daisy. She was so sarcastic and funny that I caught myself laughing out loud at times. Carson was also great. I loved the fact that he and Daisy acted so cold to each other but you could totally tell they had feelings for each other ;) Another character that was awesome was Agent Taylor, Daisy's partner. I loved their relationship and how she didn't hide the fact that she had a crush on him haha
The one down-side to this book and the reason why I deducted half a star was because I find myself getting a bit confused at times when Daisy was talking to ghosts and doing other cool stuff. I had to read some sentences multiple times to actually understand it. However the book and all its aspects were explained very well, it just took me some time to understand some parts, but I managed it!
Anyway, this book had tons of action and Harry Potter references as well as Lord of the Rings references, I just couldn't stop reading. I would recommend it to anyway :)
