I like a book that has vampires and werewolves and magic stuff in it. The mortal Instruments has all this on a grand scale. It is well written with a great cast of characters. Reading this I knew I was going to be hooked on the whole series, the way Clary is gradually introduced to the world of the Shadowhunters is done so well and at a nice pace, you don't need to know much about vampires and werewolves as this is a great introduction to the genre.

Favourite character for me is Simon, the geek somehow surviving in this world by pure luck gives us all confidence we'll survive once the vampires come out of the closet and eat the weak.
