I have to be honest, the Mortal Instruments and Infernal Devices passed Twilight and Hunger Games for me. Don't get me wrong, they're awesome, books but this one passed it by far. It has the perfect amount of action, strategy, mystery, adventure, and who could forget the romance between Clary and Jace ( and other characters). In this book, When Jace is still missing and the Clave puts the seach on lower priority, it is up to Clary to find him. She takes many risks, especially because her evil, demented biological brother is most likely with him. It's a difficult task, but it's her only choice or she'll lose her Jace forever.
