Presenting... DEAL WITH THE DEVIL...

Chapter 1

"Daddy! Daddy!" said two little girls who looked exactly same except one girl had blonde hair and emerald green eyes whereas the other girl had Red hair and Golden eyes. They were running towards the kitchen to greet their father who was bus making breakfast.

"Yes my angels!" said their father looking at his two beautiful daughters.

"Daddy have you forgotten something?" said Lucy who looked exactly like her mother except for the emerald eyes

"No! I have not forgotten anything Lucy," said Jace in a playful tone

"Think Daddy! Today is a special day "said Haley jumping up and down

"Let me think" Jace said tapping his finger on his chin as if he was really thinking "hmm! Is it Christmas?"

"Don't be silly daddy"said the girls

"Okay! Okay!" Jace said putting his hands up "here you go. Happy Birthday Angels"Jace said and put two plates of Pancakes in front of his three year old daughters.

She woke up thinking what they were doing? Whether they were fine? If he moved on?

Three years back she had made a deal with the devil literally though it broke her heart to do it it was the only way to save them...All... of them. She was pulled out of her thoughts at the door opening

"Ah! Clary it s nice to see your up."said the man whose eyes were dark and empty and had hair white s snow.

"What do you want Sebastian? Can't you leave me alone just for today?"she said

"Well someone woke up on the wrong side of the bed today," he said smirking because he knows why she was so upset

"Well! How can I since its our third anniversary together. So get ready we are going out to celebrate so wear something fancy. We leave at 10:30," with that he left the room smiling.

As soon as he left Clary started crying. Why could he not kill her? She was afraid that if she tried to kill herself then he would go after them so she got up saying to herself "you are doing this for them," with that she went to her wardrobe and opened a drawer where two small onesies were kept, she held it to her chest silently crying and whispered "Happy Birthday my Angels"

Jace left shortly saying that he was going to shower so that they could spend time together and left.

while the girls were eating Isabelle walked in"Hey my favorite nieces Happy Birthday,"

"Thank you Aunt Izzy. Now where are our gifts" they said at the same time which was freaky because they did that all the time maybe its a twin thing

Isabelle laughed and handed then two small pink and blue cover boxes to them"Here are your gifts. Its from me and uncle Simon too." "thank you aunt Izzy,"they said while opening their presents, inside each of their box was a rose gold locket that had their names engraved in cursive and it opened up and inside it had two photos one of their fathers and one of their mothers. They smiled and hugged their aunt and ran out to show their father what their aunt had given them, they ran to their fathers room and knocked and waited for their father to open the door. Jace opened the door after a minute looking fresh with his hair was damp wearing a black t-shirt and jeans and smiled looking at his daughters

"Daddy! Look what aunt Izzy got us," they said they showed him the lockets

"Wow its really beautiful," he said

"Wait there's more they opened their lockets and showed the pictures to him he immediately felt a pain in his heart as he saw Clary's picture

"Daddy?" asked Lucy

"Yes, Princess?"

"Where is mommy?" she asked and Haley nodded agreeing with her sister as if she had wanted to ask the same question.

"Uh um M..Mommy...uh... she..um..she went to save the world but she told me that she wanted me to give you both something or rather show you both something," he said as he remembered her giving him a box and telling him that on their birthdays to give them both one that was labled for each year till the were twenty.

Jace went to his room and was followed by his daughters who sat on the bed waiting for the present that their Mom gave. He opened a box and took a CD labled 'HAPPY THIRD BIRTHDAY' he took it and gave it to them "Mom told me to show you this so lets go to the Tv room and watch it."

"Okay!" they said

"Daddy ! Can Aunt Izzy and Uncle Simon come too?" asked Haley

"Sure, why dont you both go call them while I go set things up okay?"

"Okay" they said and ran to get everybody

Jace sighed and went to the Tv room and set everything up. This was the first video she made for their daughters since they could understand better only now. The first two years she left her favorite stuffed toys that she saved all these years, but now it was videos and it was hard for him to see her face and listen to her voice because he was scared that if he did he would burst into tears but he was pulled out of his thoughts as he heard his two daughters run towards him followed but Izzy, Simon, Alec and Magnus.

They all sat on the couch and he pressed Play and Clary's Image popped on to the screen

On the Screen Clary was Pregnant as you could see her swollen Belly wearing a Turquoise blue dress with her hair loose and Jace could feel his heart clench as she started to speak. God how he missed her voice

Hello Lucy and Haley,

well your dad and I finally decided on your names. she said and chuckled

well be glad that I gave you your names or else you would have been named something like Vern or Thelma or coconut pancakes for that matter. She says and pauses

wow! Your three years oldshe says and smiles Happy Birthday! I'm pretty sure that if you are like your father then you had coconut pancakes for breakfast and Aunt Izzy got you guys something that is beautiful and maybe she would take you for shopping and if you are like me you would hide from her till she gets tired because she is a demon when it comes to shopping. Don't tell her I told you that because she will kill me by making me carry all of her shopping bags. she says and the girls, Jace, Simon, Alec, Magnus laugh ….and Izzy Laughs with tears in her eyes.

I know you both must be wondering where I am right now?and I know that you must have asked you dad or anyone that question, well... I am in a different place so that I can protect you and hopefully one day I can see you both and listen to all your stories, all the funny things your dad does and did you know that your Dad is scared of Ducks... well hopefully you guys are not scared of them because then you can prank your father just ask you uncle Simon or uncle Magnus for ideas. when she says that the girls look at Jace and laugh and Jace says "Simon! Magnus! don't even think of doing planting ideas in their heads"

"Oh! Don't worry about that Goldilocks I'm sure if they are like biscuit then they will come up with ideas on their own, isn't that right Pumpkins" Magnus says winking at them

well now your three years old and must be running round the place and troubling dad and you must look like him too those same eyes and smile. When she says that they both reply saying "no we want to look like you" and Jace simply says " Hey that's not fair,"

"sorry Daddy but Mommy is much prettier," Lucy says and Haley simply agrees.

"Okay! fair enough" he replies they look back on the screen and clary take a deep breath and then starts to talk

I wish I was there but I cannot be there for you guys and I am really sorry maybe when you grow up you will understand why I was not there but I want you to remember that I'm always going to be there for you and if you feel sad you just close your eyes and think of me. She says this and the adults could understand how much Clary was fighting so that she doesn't cry. And if you want to talk to somebody then you could always go to aunt Izzy, uncle Magnus or grandma Jocelyn or grandpa Luke and always remember that your father loves you very much and will protect you from any harm and I want you to make sure that your father doesn't make fun of your uncle Simon and please stay away from uncle Magnus's glitter because that is very difficult to get out and the most important thing that I want you to remember is that I love you so very much and you both and your dad are my world and I want you to both to give dad a kiss from my side and tell him that I love him and tell Izzy, Alec, Magnus, Simon, grandma Jocelyn, grandpa Luke and grandma Maryse that I miss them. I think you guys understood that because you both are kicking me from inside. She says while crying and so does everybody silently in the room. I hate that I have to leave but I love you and Happy Birthday my Angels I hope you have the most wonderful day today and wonderful years ahead. Bye with that the screen becomes blank and the Gang are in tears while Lucy and Haley hug their father and say "Thank you Dad for giving us Mom and we love you and so does Mom" and they kiss his cheek "I love you too both of you very much. Why don't you take aunt Izzy and go out to grandma Jocelyn and Grandpa Luke's house they called asking for you both," Jace says and smiles at them. They nod and drag Isabelle and Simon out the door followed by Alec and Magnus. Jace was going to take out the disk when the screen flashed and Clary began speaking but this was addressed to Jace

Jace I don't know if you are seeing this or not but I have to tell you something I knew if I told this to you before you would react but just her me out I know what is going to happen to me once I go to Sebastian so after Lucy and Haley are born I asked Magnus if he could put a spell on me so that he could not abuse me or anything and hopefully it works but this is just a way for me to find time to find a way of binding our lifes together like the spell he put you into except he doesn't control me and I don't control him because if that happens I don't know what would happen but if I do I will be able to kill him once and for all and we don't have to worry. Once I kill him we will be free and you will know and I will be able to see you and our kids grow up and will be able to protect you. I love you Jace! Bye...

Jace stared at the screen for a few minutes and then his heart sank realizing what she really meant she was going to bind her life with Sebastian and was going to kill herself. Jace's eye widened and he pulled his hair in frustration "NO no no no this can't be happening Clary" he screamed this very day he received two beautiful angels but lost the love of his life this very day but promised himself that he was going to get her back ALIVE and he was going to kill Sebastian Once and for all
