What would happen if the two very different shadowhunter groups met? Will there be drama, will there we romance? What will happen when the Londoners travel to new York, present day?

Dear reader, am I not the only one who has wondered what it would be like if the shadow hunter groups collided? So, before you ask me about how they got here, close your eyes. Wait, no, you need them open to read. Imagine a portal that can bend time and space to allow this? Great. Created by none other than Magnus the Magnificent, Tessa, Jem, Will, and Jessamine travel through the portal. They find themselves in the New York institute, surprised to find the gang waiting for them, wondering what Magnus had planned. You will have to have read up to City of Lost Souls for TMI and have to read TID (Jessamine hasn't betrayed them in this story). Sorry if anyone's OOC, but I'm not the author, so I can't get into it as well.

No matter how much, I beg, plead, get down on my knees and weep; Cassie still won't give me the Mortal Instruments OR the Infernal Devices. Nor do I own any of the books, poems, songs, or companies/buildings mentioned. *sigh* no, I just write about them.

Chapter 1

"All I'm saying, Isabelle, is that I would rather fight in a cardboard box than that awful shirt- ahem- dress."

Izzy let out an exasperated sigh. "Really Clary, you should see beyond shadow-hunting gear for demon-hunting. I mean, look at what I fight in." Alec scoffed. Jace put a hand to his heart and pouted at the girls. "Why don't you ask me? Don't girls dress up for their boyfriends? But nobody ever asks for Jace Lightwood's opinion."

Izzy rolled her eyes. "Nobody wants your opinion, Jace. Actually, I have a few ideas of where you can put it. But, you're going to say it anyways, so go ahead." He grinned, expecting the answer.

"Personally, I think Clary looks sexy in shadow hunting gear," Clary beamed at Izzy ", but I'm always open to some more…flavorful options." Clary's smile fell from her face as she hucked a pillow at Jace.

"Whose side are you on?" Clary sputtered. "I mean really, Jace! If only you could have seen the horrors! It was pink, and had ruffles! Pink, Jace! Pink!

Simon poked into the conversation. "So, uh, guys…uhh…When does Magnus get here with the 'surprise that we will all absolutely love'?"

They had almost forgotten about Magnus while they were discussing Clary's closet. The gang had been ordered to wait in the library until he got back. It had to have been important, because the warlock had shortly disappeared through a hazy portal. He must have been up to something though, because he wouldn't tell even Alec where he was going.

...

"If I step through here, Magnus, are my virtues in question? I do recall you kissing me once. Pity, too, I had expected candle-lit dinners and poetry from the balcony." Will, of course, had taken it upon himself to make sport of the poor warlock. Tessa, luckily, hadn't heard. Busying herself with a personal favorite- A Tale of Two Cities was hovering near her face.

"William, honestly, let him alone." Jem rested a hand on Will's shoulder. "Besides, I believe Henry has a few questions for Magnus." Henry was furiously ripping away the inner workings of Magnus' cell phone, which had travelled with him from New York. He was mumbling something about the impossible codes and design.

Magnus looked concerned for his phone. He reached towards Henry. "Ah, be careful with that. It only came out this month."

"Just leave it, Magnus." Will offered his arm to Tessa, "Shall we?"

Every corner of the grand library was flooded with light as a great portal opened before the large wooden desk with a flash of light. Quite opposite to the usual, Church went careening towards the disruption, not away from it. As the light faded down, four figures could be seen, two girls, each with dresses that were floor length, bound up tightly, and most old fashioned. Isabelle visibly scrunched her face up at the sight of the dresses. Of the two boys, one was laughing, and one was clutching his hand to his chest.

"I think your vile creature gave me a disease, James!" The boy who was laughing was holding Church to his chest, stroking the cat with a familiarity that no-one had with Church. The boys had not noticed any of the Shadowhunters yet.

"I can't believe he found me! How did he even live this long? Oh, that's a good kitty Church!" The boy looked up, his shocking silver eyes meeting Jace's. The boy's pale hair matched perfectly with his eyes, they were not just a trick of the light. "William…I believe we have guests."

Jace coughed. "Technically speaking, we are the ones with guests. You're in our institute, after all."

Clary popped up from her spot beside Jace and approached the girls. You could hear Jessamine gasp when she saw the spandex training pants that Clary had worn to the institute. "Nice to meet you, I'm Clary." She gave a little wave, while Tessa's hand stuck out into the air.

"Um, Tessa…Tessa and Jessamine"

"ARE YOU A PROSTIT-"Tessa clamped a hand over Jessamine's mouth. Clary turned a scarlet that rivaled her hair, and Jace came to her side.

"Uh, no. Things must be different where you came from. Clary very much has values. She throws it in my face often. Too often."

Will looked up from his conversation with Jem, and strided over to the group. "William Harondale- expert charmer, demon hunter, shockingly handsome. Sorry girls, taken."

Jace looked a bit surprised. "Jace Herondale,-a ladies' man, sarcastic genius, and one superior shadowhunter.

Magnus had staggered over to Alec, and lay down on the floor. Alec and Izzy were arguing over the blanket Izzy had, Alec pointing out that Magnus needed it more than she did. "Izzy! Look at him! He's exhausted from the spell! Don't make me do it, Iz…"

"No, Alec. Go away. He can just zap one can't he?" Alec exhaled and pounced onto Isabelle. Tessa let out a small 'eep' while Jace, Simon, Clary, and Church all looked on in interest.

Simon leaned over to Jace. "My girlfriend can take on your parabatai any day." Alec had pinned Izzy to the ground, wrestling the blanket out of her grip. Jace just smiled evilly at Simon

The old-fashioned shadowhunters were all horrified by the aspect of a man wrestling down a woman and prying something from her reach. Jessamine gasped, loudly, when the shortness of Isabelle's dress was revealed. A strapless, mid-thigh number with a silk ribbon around the waist seemed to be Izzy's latest choice.

This wasn't going to be easy.
