Not going to rate this, because it's not a novel or anything. I've been slowly reading this for over a year and have really enjoyed it! It helps to touch on things that we've never heard/learned in the novels. Also a great resource for a shadowhunter fanfic writer such as myself. Some parts could be a little boring - but that's history for ya! Plus, Clary, Jace, and Simon writing and doodling in it was a cool touch.
