This was, of course, a wonderful book! What else can you expect from the world of Shadowhunters? It's quite a different world from Mortal Instruments & really interesting to see some of the history surrounding the Nephilim. I am completely torn between Jem & Will. (Which never happens - I usually hate love triangles) This is one of the few times that I can see the attraction to both of them & couldn't possibly decide. Jem is so loving & kind, but the fact that he is a fierce Shadowhunter keeps him from seeming weak. Will is absolutely impossible! But irresistible, as well. And both have secrets that will just break your heart. Once again an amazing story from Cassandra Clare!
