"Mum!" The deep voice of eighteen year old Jonathon Morgenstern rang through the walls of his massive home. "Jace is here, is it okay if he stays for dinner, we've got stuff to do." Jonathon looked over at his golden eyed best friend and grinned. Him and Jace and been best friends since Jonathon had moved to the sleepy old town of Idris when Jonathon was 8. Jace was gorgeous, he had features better than a supermodels with golden eyes, hair and skin and a build that could make even the straightest man swoon. Jace was the adopted son of Maruse and Robert Lightwood and had thee siblings : Isabelle, Alec, and little Max. Jonathon had a sister of his own but he had not seen her for many years after the rocky divorce of his parents when he was eight. His douchebag of a father had managed to gain custody over his sister while Jocelyn had won Jonathon. Jon had inherited the white blonde hair and dark eyes of his father while little Clarissa (Jon's younger sister by three years) had the flame red hair and shocking emerald eyes of their mother. Jonathon was quite content with his life. He lived in a nice town, was co captain (alongside Jace) of the football team and had girls falling over themselves to go on a date with him. He lived with his mum, Jocelyn and her second husband Luke in a nice big white house on property outside a small country town.

"Ok!" Jocelyn called back from her art studio upstairs. She was always up there painting away for dawn through dusk. "Can you bring me some chocolate biscuits?" She called down again. Jonathon rolled his eyes at his mums love for all things sweet.

Jon and Jace strode through to the kitchen all the while gossiping like girls as Jon put some cookies on a plate. The packet was full but once Jon had put a couple on the plate and he and Jace ate the rest it was empty. The boys had massive appetites being the football players they were. Jonathon raced up to drop off his mums cookies then joined Jace in the living room were he was setting up the Xbox.

Sitting at the big mahogany dinner table that Jace was entertaining every one with his usual snarky ness when Jocelyn sat up straighter and her eyes brightened tremendously. Setting down her silver soup spoon she grinned at her company of men and clicked her fingers in attempt to pull their attention away from the golden haired lad sitting across from her son.

"I almost forgot!" She said with a smile, "I have some wonderful news!"

"What is it mother?" Asked Jonathon, leaning forward in his chair a little.

"Well," Continued Jocelyn "I was going to wait till it was just us but Jace is-"

"Practically part of the family I know" Cut in the blonde, Jonathon elbowed him to shut up.

"Anyway, Clary is coming to stay with us!" Luke almost choked on his wine and Jon did a double take.

"Clary," Jace said, "Clary as in Clarissa?"

"Yes" Said Jocelyn.

"When is she coming to stay with us, how long is she stating?" Asked Jon, he was excited to see his little sister again after such a long time but he wondered if she would still like him or his family.

"I think she will be coming in about a weeks time." Jocelyn said "It's quite short notice but my shit of an ex husband is moving his business to Dubai and he won't have enough time for her so the court said she was to stay with us for six months before things quiet down for Valentine. She'll be in sophomore year at your school, isn't that the same year as Issy?" This last question was directed at Jace.

"Yeah," was the reply "I'm sure Is will be happy to take care of her."

"I cannot wait to meet her!" Said Luke grinning as he kissed the back of his wife's paint splattered hand.

"I know," said Jocelyn with sadness in her eyes "It's been ten years...

As Jon was driving his best mate home after dinner in big black jeep he thought he might explode from happiness at the thought of his sister coming to stay. He had not seen her in such a very long time and she might have changed in those ten years.

"I wonder of she's hot" Jace interrupted. Jonathon went quiet all of a sudden and he curled his long fingers over the wheel. Turning his white blonde head towards his friend there was a very dangerous glint in his eye.

"Jace" Jonathons voice was a threatening growl, " This is my sister we are talking about. You will not touch her if I can help it. I know what you do to girls. Sleep with them once or twice then break their pretty little hearts and move on to the next one. If you break her heart, by the angel I will ruin you." Jace didn't doubt his friends promise. Jonathon was a very protective person and he had, on many occasions, ruined someone's whole existence for wronging one of his friends.

"Jonathon," Said jace in a serious tone, " I swear on the angel that I won't hurt your sister, you know me and I would never do that to her , I swear"

Jonathon looked suspicious but turned his eyes back to the road pulling the car into the Lightwoods street. "Ok whatever now get your ass moving blondey we've got football tomorrow morning. Jace waved goodbye to his friend before jogging up his front steps and knocking on the door. It swung open to reveal a very pissed looking Isabelle who seemed to be in the middle of removing her expertly applied makeup.

"Damn it Jace! How many times have I told you to get a key!" She exclaimed, letting her brother in.

"Sorry Iz," Said Jace, following her through the dark hallway lined with various doors before reaching the main room that stretched across the back of the house. It was furnished nicely with an open kitchen to the left and a couch area to the right. A white, red and grey Persian rug sat beneath red couches in front of a massive flat screen Tv that was currently playing Maxs favourite marvel movie Captain America.

"Hey Maxxie " Jace said. "Guess what?"

"What?" He muttered half-heartedly.

"What?" Said Izzy with a little more interest. Just then Alec walked in with Maryse and Robert.

"What's what?"

Said Robert, as Maryse walked over to receive a hug from Jace. "Alec,Your mother and I were just moving some things around in the garage, anyway what's new?" Robert finished jokingly. Jace thought that while he had always seen Maryse as a mother he had never really come to see Robert as a father, especially after Max's accident. Jace had found out that Robert had been seeing another woman behind Maryse's back. Maryse had figured it out, being the smart woman that she is, and told Jace that they had made it up. But Jace was not stupid and he could tell that there were still miles of space between them.

"Yeah what is it?" Said Max, wheeling himself over from the couch.

"Welllllll" said Jace.

"Oh just spit it out already!" Cried Issie from the bathroom. She really had an incredible sense of hearing.

"Oh whatever Jonathons sister is coming to live with them for a couple of months," Jace's revelation caused a few stunned gasps. The whole family knew about the divorce of the century, he'll the whole country knew. Valentine Morgenstern was one of the most influential business men in the world and the fall out with his rebound artist wife was broadcast around the globe. Even little Max knew about it.

"Isn't her name like Clarissa or something?" Jace replied to his sister that it was, and added "She will be coming to the hellhole of a school we attend so she' ll be in your year Isabelle."

This sourced a squeal of delight from said sister. She instantly began chatting away to no one on the idea of a shopping partner who wasn't a total idiot. Alec smiled at Jace before bringing out his phone to text his boyfriend Magnus the news.
