I have this bad habit of rating books as I read along. This for me went from 4 down to 2 so I settled on 3. I liked the idea in this book, the characters, the mythology and yet I couldn't fully get into it at times. More than once I would read a sentence and don't remember the last five pages. My mind was instead thinking about grocery shopping. So it's easier for me to point out what I didn't like over what I did like. For example for all the interesting mythology in this book I thought the ghosts (or haints) were very limited. Every other bad guy was a draugr (aka zombie). An entire mythology of ghosts and we only get two types? 
 Another thing that kinda got to me was that the pov shifts between Dan and Leif and sometimes I had to reread the same scene only from another pov. Sometimes it fit perfectly. Sometimes it felt respective. 
 I also saw every twist in this book coming a mile away. I'm the type to like the paranormal aspects over the romance and this relied heavier on the romance. And that part is good. 
 Now for what I did like most was the characters. I can tell these characters are really fun to play with. Specially Dan with his tone down angst. I just wished Leif had used his full name, Dante, at least once :P
