Author's Note:

Hiii guys! So, this is my modern version of the Infernal Devices story. Well, seeing as I have no talent with writing such awesome action scenes as Cassandra Clare. I hope you'll still enjoy my story which will focus on the love triangle between Will, Jem, and Tessa. :)

DISCLAIMER: I DO NOT OWN THE INFERNAL DEVICES ALL CREDITS TO THE GREAT CASSANDRE CLARE *hearts* !

Chapter 1: Homecoming

France, hours ago

"Tessa…my Tessa…it's time to wake up. We'll be late for our flight." she groaned as she heard his soft velvet voice. As she opened her eyes, his face was hovering over hers, which made her smile.

"Good Morning to you too, my Jem." he smirked at her sleepy tone and helped her up to a sitting position. They were in their hotel room in France, Paris, to be exact. Today was their flight to America. Magnus was expecting them. She looked at Jem with pleading eyes, "Five more minutes." And he seemed to get the message. Two years together, he's observed that she isn't much of a morning person.

"As much as I want to give in, love. You know we can't miss our flight. Magnus will be disappointed." she pouted at that which he chuckled at.

"Don't make me carry you to the bathroom, Tessa. I will do it if I must." he added as he continued with what she assumed he's been doing since he woke up, packing up their stuff. Jem had always been the perfect gentleman. With a sigh, she got up and got a towel. She was in her green silk nightgown, a gift from Jem's uncle from China last Christmas they've been there to visit. She made her way towards Jem and gave him a quick kiss before heading for the shower.

New York, present

Will Herondale was walking briskly in the busy streets of New York. Magnus insisted he come today for big news. By news, he knew that Jem was coming back. His brother was coming back after three years. It was hard to partways but he couldn't let his feelings stand in the way of Jem's dream and he wanted to take up music in Europe. There was more to life than Shadowhunter duties. At last, he arrived at Magnus' townhouse. He rang the doorbell, noticing that his palms were clammy. The door opened to reveal Magnus.

"Nice of you to drop by, William." he greeted and gestured for Will to come inside. They took their seat at Magnus' sleek leather coach.

"Came as soon as I got your call. When's he arriving? Do we have to fetch him at the airport? You should've told me. I didn't bring my car. By the Angel, Magnus! Why are you laughing?" he looked at the chuckling man beside him with frustrated sapphire eyes.

"If only you can see how this news has taken its toll on you. You look disheveled. Does this news of James returning really that important? You could've gone after him if you'd wished but you did not." with this reply, Will's eyes closed and he brushed his hand through his hair which was wet from sweat.

"I came as soon as I can. You know I couldn't just abandon the Institute. Charlotte would kill me. So when is he getting here?"

"In a few minutes, I suppose. Also, I believe he's bringing someone along with him. A girl whom he had met by chance in his brief stay at Cambridge." a smirk graced the warlock's face. Surely enough, the news had taken the blue-eyed Shadowhunter aback for he stood up so hastily.

"By the Angel, a girl! Why hasn't he spoken to me of this in all the times we've exchanged calls and emails?"

"That I do not know of. But if you must know, why not ask him yourself?" Magnus said as he lazily looked at his phone and to Will again.

"He's here?" he asked looking more anxious than ever.

"He's well on his way. With Tessa in tow."

She looked at the window of the cab and her eyes passed by the ever-higher infrastructures of New York. It was her first time in America. A new continent that she is determined to know of. She didn't hesitate the time Jem had asked her to accompany him to New York to meet his family.

They were in a café with a lovely view of the Eiffel Tower. She was eating strawberry shortcake when Jem had asked.

"Tessa, what would you say about going to New York with me?" he looked into her eyes with his hazelnut ones.

"Why are we going there? I suppose I can." she smiled at him. The idea of making the most out of her break was exciting. New York would be the highlight of it. She could feel it.

"I want you to meet my family." he returned her smile as he said so.

"I thought your uncle was in Shanghai?" she asked thoughtfully. Jem had once told her his mother was Chinese and his father was British. But it was sad that they died when he was just 10. The only known family he has was his uncle.

"Well, my uncle is there. But I wanted you to meet the family that has adopted me since I was 12. My family in the New York Institute which is composed of Will, my parabatai , his sister, Cecily, and Charlotte and Henry." she took his hand.

"I would love to meet them."

They stopped by Jem's flat first to leave their luggage. Tessa couldn't help but wander around. She saw pictures of Jem with a boy. The boy was raven-haired and with the most beautiful blue eyes she has ever seen. He was with Jem in almost every picture. The only exception was the Carstairs family picture. A pair of familiar arms encircled themselves around her waist.

"She's beautiful, your mother. Now I know where you got your hazel eyes." she felt him sigh as he buried his head on the crook of her neck.

"Indeed, I get that a lot." he whispered. He let go of her and checked the clock hanging by the wall.

"Magnus is expecting us. We better get going. I promise we'll rest after this visit. Forgive me. You must have jetlag. We could go to the Institute tomorrow to meet up with Will and the others." she shook her head and took his hand to twine it with her own.

"I'm fine. I'd love to meet this friend of yours. Not all Shadowhunters are such good friends with warlocks." With that, they went and got on Jem's silver convertible.

After what seem like forever of waiting and pacing around, Will finally heard the doorbell ring. He raced for the door, stopping as he reached for the doorknob. He took a deep breath and gently opened it. The first thing he saw was not Jem for he was standing on the far right. He saw a girl who had the most enchanting gray eyes imaginable and gorgeous curls of brown hair framing her delicate face. The girl, in turn, looked shocked at seeing the boy she was just admiring at pictures a while ago in the flesh. She broke away from their staring contest and turned to Jem. He looked amused.

"Is he Magnus Bane?" she asked curiously for Will's marks weren't visible with his attire today. This made Jem chuckle and Will finally turned to his parabatai.

"This is my parabatai, William Herondale. Though, I am not surprised that he would be informed of our arrival. Will, let me introduce you to Miss Theresa Starkweather." his arm wrapped at Tessa's waist as he turned to his parabatai.

"Nice to finally put a face to Jem's Will. He talks an awful lot about you." she explained and she held out her hand. Will was still starstruck that it took him a while before he shook hands with Tessa.

"Forgive me for my rudeness, Miss Starkweather. I'm just having trouble absorbing the sudden return of my brother, James." he turned to the still smiling Jem with a glare and look of hurt. Jem let go of Tessa for a moment and hugged Will.

"Come now, Will! I know I've been so cruel as to not visit you for a long time. But believe me when I say I've missed you a great deal when I was in Europe. I got to visit the London Institute as well while I was there. Ah, the memories we had there." he felt Will heave a sigh of defeat and return his hug. Tessa smiled at the two knowing that Jem truly loved Will like he really was his brother even if they weren't related by blood. Just then, Magnus emerged from the living room with a playful smile on his face.

"How rude of you, William. Not having to invite our guests in. Pleased to meet you, Miss Starkweather. I am Magnus Bane." he held out his hand as Tessa reached to shake his. Instead of giving the usual handshake, Magnus kissed Tessa's hand that brought an annoyed look to Will's face. "Well, well. This is interesting." he thought to himself as he let go of Tessa's hand. She blushed at the warlock's gesture.

Will now found himself exhausted at his flat's carpeted floor. He got too lazy to lay down the couch and to drive back to the Institute. He was sure that their maid, Mary, could handle things for just one night. But, he decided to send a text saying, to check up on Cecily when she slept for weapons on her bed just to be sure. The afternoon went and passed with Jem telling him and Magnus about his music and how much he improved. Some of his professors even tried to refer him to music producers in which Jem declined. Even though he loved music, his first love will always be being a ShadowHunter. He also told them of the magic that happened between him and Tessa. Tessa. He just couldn't seem to shake her off his mind. When he closes his eyes, all he could see are her glistening gray eyes. He violently brushed his hair with his fingers in frustration and let out an exasperated sigh. He just couldn't understand why she has this effect on him. Girls were never a stranger to William Herondale with his blue-violet eyes and raven hair. But Tessa was different and he just couldn't fathom how. Maybe its just cause she's Jem's first girlfriend and his brotherly affection towards Jem is rubbing off on her as well. "Yes, that's it!" , he thought and dismissed the subject completely. He closed his eyes and surrendered himself to a much-needed sleep.
