Clary finds out she has ability to see people no one else can: demons, Shadowhunters, vampires and the like. This comes in handy when her mother is kidnapped and Clary is attacked by a demon. She gets help from 3 Shadowhunters (Jace, Alec, Isabelle) whom she meets when she saw them killing someone.I’m having little mixed feelings about this one. I liked it but I’ve heard so much raving about this that I was waiting something more. It started kinda slow and I kept waiting something to happen but it got better in action wise towards the end. But it seems I’m the only one thinking that so don’t listen me...Surprisingly there wasn’t any annoying characters even if Simon was boring but wasn’t huge fan of the triangle between Simon, Clary and Jace. And I wish there had been more Alec! And how could you not like Jace? All in all it was good book if not great and I’ll definitely read the next one.
