I have not read the novel version of this book so it was a little weird to read the graphic novel first. It was a little harder to get a handle on the story and who everyone was at first (a lot of times everyone in graphic novels looks the same to me). I think the story would have been more confusing if I hadn't already read the Mortal Instruments series. There were a lot of things that weren't explained that would be confusing if you had no familiarity with either the Mortal Instruments of the Infernal Devices series. I have this novel at home and after finishing the graphic novel, I think I'm going to bump it up to the top of my To Be Read list.
