I was taken by the title, but the text doesn't have the same urgency. I mean, the MC is vengeful and bitchy, but kind of without the in-your-face panache of the title. The mystery is so much of a surprise that it's kind of unbelievable, and the ghost universe doesn't make a ton of sense. 

Also, the pdf of this digital ARC is a drag. In the NetGalley reader, I couldn't even change it to white on black. That worked in Bluefire Reader, but I couldn't change the print size. My near vision is weak so I had to change the size back to regular every time I wanted to turn the page.
