This book is different from the other books in this series that I've read so far in that Gretchen doesn't really play a role in it! It's a relieve actually, now Chelsea Cain focusses on the solving of an actual crime instead of just the relationship between Gretchen and Archie.
Because, I did like to see the development in there (not for the better), but now I read a more 'normal' novel without it, it was actually a nice break, and a lot better for the plot. The writing style is still very fast, which helps to make this again a nice and quick read.
Note: I read a Dutch translation of this book
