A/N Hello Mortal Instruments fans and whoever else is reading my story! I do not own Mortal Instruments or the characters, I just play with them.

Chapter song: Poison by All Time Low (shout out to all you ATL fans!)

Summary: A shadowhunter, beaten up and dying by demon poison, show up at the New York Institute beaten up and bloody, with a nasty past. So, even with that past, can the Lightwoods help her when demons suddenly are coming from the ends of the earth to take her out? Meanwhile, how will Jace deal with the rising feelings inside him? Alec and Magnus are already together, but other than that City of Bones has not happened.

A girl walked through the streets of New York in the dead of night, constantly looking behind her. She's terrified, but yet no one saw her. Suddenly someone reached out and pulled her into an alley. There, in the alley, were eleven Ravener Demons, poison dripping from their pointed teeth. The words, capture, not kill, hissed through their vile mouths. They converged on her.

She threw her bag off her shoulder and pulled a seraph blade out of her belt. Quickly naming it, Raphael, she attacked the attacking demons.

In minutes, even though it felt like hours, she defeated them, leaving the alley coated in ichor. Knowing she's running out of time before the poison from her bites, three of them at least, started taking over; she grabs her bag and runs. Even though she's running now, no one sees the bleeding girl. She sees the Institute in the distance and she knows she's almost there. Just as she thinks she's going to make it the demon poison kicks in and she crumpled to the ground, crying out in pain. But she sees the Institute and knows they will help her. So she dragged her uncooperative body towards it. She managed to get to the gate.

Standing up, even though she was in copious amounts of pain, she shoved the gates open. She got to the door but knows knocking will take too long. So she called out.

"By the Angel Raziel and my Shadowhunter blood I command these doors to open!"

The doors sprung open wide and she made her way inside. Knowing everyone was sleeping she tried to be quiet and get to the elevator, but she couldn't help it. She collapsed into screaming fits as the venom took over her system. She barely managed a "Please! Someone help me! PLEASE!" Her abandoned bag left outside while the thrashing girl struggled.

Jace Wayland was slightly annoyed when a high-pitched buzzing noise woke him up, it seemed to go in lulls and bursts, but when he heard the noise going, "Please! Someone help me! PLEASE!" he noticed it was a girl screaming.

Jumping out of his bed and his sleep-induced-haze, he raced down the hall and pounded hard on Alec and Isabelle's doors. He raced into the elevator. Never had he hated the elevator so much. When he finally got to her she couldn't even speak. He didn't even know why until he saw the bite marks. Eleven in total covered her body.

"Maryse! Robert! Come quick! Someone's hurt! Get Magnus! It's demon poison!" Jace called.

He bent down and picked the girl up. Her head whipped to his in a head butt and he almost dropped her. She fought to get out of his grasp when instantly she stopped, as if remembering he was here to help. When she stopped fighting him he noticed how she had dropped her seraph blade. So she was Nephilim.

He had carried her upstairs and had just laid her in an infirmary bed when Magnus rushed in. Looking down at the thrashing girl he said, "What happened to this poor girl?"

"No idea," Jace replied, "but it doesn't look pleasant."

"No shit Sherlock!" Izzy replied. "How can you even make a joke about that you -" she was cut off by a raspy voice from the bed.

The girl had managed to stop thrashing enough to say, "Raveners…" and then started thrashing again.

Magnus's eyes widened at the severity of her wounds, and said, "Out. Out. Out!" Jace, understanding the urgency, grabbed Alec and Isabelle and pulled them out.

"What was that about?" Alec said.

"She girl was obviously attacked by Ravener demons, knew where the Institute was, came and asked for help. Though begged and screamed is a better word for it." Jace said.

"I know that. But why would Raveners attack a Mundie? And how did she see and know where the Institute was? Though the big million dollar question is how did she get the doors open?" he replied

"Because she's a Shadowhunter!" Jace and Izzy said at the same time. They scowled at each other before Isabelle continued.

"I saw her marks when Jace was carrying her."

Alec looked at Jace expectantly. Jace sighed. "She dropped her weapon when she head-butted me. I almost dropped her! She's got a survival instinct that only a Shadowhunter could have. Besides she's got muscles only we have. So. Obviously she's one of us."

A blue flash that came from the girl's door blinded the three Shadowhunters in the hall for a couple of minutes. When they got their sight back Magnus was standing in front of them, his legs shaking. Alec went over to help his boyfriend when Magnus said, "The girl will be fine. Some past trauma has rendered her unconscious I'm afraid." Alec helped Magnus toward the door, but stopped and called to Jace, "Tell mom and dad where I am! Thanks Jace!" with that he and Magnus stumbled out the door.

Izzy laughed. "Magnus will be exhausted tomorrow morning don't you think Jace?" he laughed at her barely hidden suggestion.

"He will that's for sure! So. What do you think of this? Girl shows up in the middle of the night, almost beaten to death and screams for help. How do you think it happened?" he asked.

"I don't know Jace, but she seemed terrified under all that screaming. How much venom was in there? I've never heard a shadowhunter scream so loud. Poor girl. We don't even know her name! I'll call her Anne. Anne must have gone through so much pain. There had to be like twenty of them! How did she ever make it past that?" she shuddered and walked away.

Jace laughed at her crazy nonsense, but once she was in her room he slipped into the mysterious Shadowhunter's room.

She looked peaceful lying down and sleeping. It was then that he noticed how beautiful she was with her fiery red hair framing her small, pale face, and her petite body that hid how strong she really was. As he was staring at said petite girl, he felt a need to protect her. He didn't know why, and that scared him.

~NRNH~

She woke up in a very clean room. It must have been one in the Institute. She groaned as she felt her head throb. How much venom was in her system? She never lasted that short of a time!

"Hey, sleepyhead! Howya doin'?" a voice asked from the side of her bed. She looked up at the man who asked.

"Worse then ever. Guessing from your clothes, you are Magnus Bane?" the mysterious red-head asked calmly. She had seen him before, but when she was still very little.

"Yes. How did you know about my clothes, young one?" Magnus asked, slightly shocked. The girl just smiled and jumped up to give him a hug.

"It's me! Clary!" she said. The warlock's eye grew extremely round.

"Clarissa Morgenstern?" Clary smiled.

"The one and only! Miss me?" a gasp broke apart the hugging warlock and shadowhunter. Jace was standing in the doorway, gaping at them, her specifically.

"Morgenstern? As in Valentine Morgenstern?"
