Chapter 1

"JONATHON CHRISTOPHER HERONDALE GET YOUR BUTT DOWN HERE RIGHT NOW!" the screech of Isabelle Lightwood echoed right through the halls of the New York Institute all the way up to the training room rafters where the accused party was hiding out, out of the firing line of his sister, talking to his girlfriend Clary on the phone. "Jace what did you do to her now?" Clary asked exasperated. Ever since the Dark War ended Jace had become almost insufferable with all the pranks he pulled on people. Just the previous week he had taken all of Magnus' glitter and burned it on him. "Nothing much I just 'accidentally' placed bleach in her shampoo" he replied simply "WHAT?!" Clary choked. No wonder Isabelle was so angry. It was a known fact to all with a wish to live that Isabelle prided herself on her dark raven black and that messing with it would without doubt end up with one person (NOT Izzy) injured and needing quite a few iratzes. Of course though this didn't faze Jace because it was also well known to all, that he himself was one of the greatest Shadowhunters of the age so he just did it anyways. Just then the training room doors flew open and a very, very angry Isabelle, who had hair so white it rivalled Sebastian's, stalked in with a murderous look on her face. "Clary I have to go. Izzy's here and looks ready to kill. You better start looking up your white clothes" Jace murmured down the phone. Clary chuckled before replying "Ok then. I'll see you tonight" "See you then" he replied and hung up.

"Hey Izzy what happened to your hair?" he asked innocently. "Don't you 'what happened to your hair' me. I swear if you don't come down here right now I will go into your room and paint it pink!" she threatened. Weighing up his options Jace decided to protect his room from the wrath of Isabelle. He jumped off the wooden beam he was perched on and dropped down to the floor, landing on his feet right in front of her. A silent message passed between them and suddenly they were fighting. The fight however was short lived as just seconds later Maryse Lightwood came in and pulled the two off each other. "Stop acting like two year olds and get a grip" she said sternly. "Someone call Clary and Simon. The Clave has a mission for you. It is regarding Sebastian"
