Good book but not better than Mortal Instruments although by the time I finished the entire series I ended up liking it better than Mortal Instruments. I like that it takes place in the past in London. The characters were interesting. Will or Jem...Jem or Will...always a choice and I of course always seem to choose the other guy JEM! I love him. Will clearly has some issues affecting him but so does Jem so I hate when that is an excuse to be an ass. Look forward to learning more about their backstories in the next book. Jem is perfection.
