It is a slow book until the last 100 pages. I just wanted to stop reading it, but knew I had to finish it since I hate not knowing how books end if I don't finish them. I would like to know everything comes to an end in the sequel to Night Sins, but knowing that the second book doesn't invlove the same characters and how slow the first book was I'm not sure I will choose to read the second one. Honestly, I would not recommend this book, but if you are looking for a mystery book I would recommend a book by Lisa Gardner or James Patterson.
