I LOVE this book. Seriously, it's my number one. Well I have two or three number one's, but still, you get the picture.
The whole series was great. It's different the the usual vampire/werewolf meets girl, they fall in love, big battle towards the end against some evil vampire/werewolf and then a happy ending, possibly resulting in a sequel. Don't get me wrong, I actually like books like that, as long as they have a bit of variety to them.
Now, back to this book. It does have vampires, werewolves and other paranormal creatures, but mixed in with some kick-ass Shadowhunters.
At first, I was worried that the lack of first person would deduct from the experience, but I couldn't have been more wrong. It didn't make a difference, and it did give us a few chapters focusing on Simon or Jace, aswell as Clary. Damn, and now that I've mentioned Simon I must start on him..
Simon-The first vampire that can walk in the sunlight a.k.a Daylighter.
He's been in love with Clary since they were kids, and it breaks his
heart to see her head over heels for Jace. I was so glad when he
found Maia, and I hope it carries on with them in the fourth one.
He was my favourite character, but it doesn't mean that I like Jace and Clary any less, or any of the other characters. The characters develop throughout the series, which is always nice in ongoing books. They adapt to surroundings, their new life and eachother, and have realistic personalities.

I can't wait until the fourth book, couldn't believe my luck when I discovered there were to be 3 more! And of course the Infernal Devices. Mmmm... :)
