This book was so good that I wouldn't put it down, from start to finish it was amazing. It as written by Cassandra Clare. The main characters were mostly Simon and Clary in this one. They each have trials and things that they go through and it had me dreaming about it when I had to go to bed. There wasn't anything I didn't like except the fact that the end is a cliffhanger so if you don't like those beware!
Violence:3 out of 5 a few people are killed. But not to graphic.
Intimacy: 3 out of 5 Clary and jace have a couple of part were they kiss.
Over all: 4 out of 5. Very very good, highly recommended for all ages.
