Obviously, this is supposed to be a non-fiction book, so it took me a while to read through it. Having read many of the Shadowhunter books, I also knew most of it, but I still appreciated this book. The added commentary by Clary, Jace and Simon added some humour and I appreciated all the art work and drawings in here. That being said: If you're not a fan of this series, you shouldn't read this book either. quick question though, why are the shadowhunters only referred to as "she" in the book and not "they"?

Did I really need this book? - No. Have I learned something new? - No. To me it felt like a compilation of all the information one can read throughout TMI and TID. As soon as a question arised that wasn't answered in the previous books, it was said that the answer is not know by the Clave. Very clever... Yeah. Moreover why the heck are Shadowhunters and Inquisitors (in the Inquisitor section) called "she"?! It's not like the thing was written marely for Clary (at least one should consider that this Codex should have been written for every Shadowhunter)
