The characters are interesting, I love Jace! I want Clary and Jace to be together, I hope in the next book they find out it was all a lie and they are not really brother and sister; I really only want to continue to read the series in the hope that this is true. I don't like the decription of some of the demons. 
 "....a monster with the legs of an elephant and the head of a mosquito.." 
 Guess I just dont have that much of an imagination, but when I read stuff like that I kind of get sucked out of my fantasy world and realize I'm reading a book for teenagers and I'm not really some kick ass chick in love with a supper hot guy who may or may not be my brother. :)
