So basically this is set in the mortal instruments world just after city of bones, when Jace finds out that Clary is his sister! however the events that happen in this fanfic do not actually happen in this book but come from my imagination

I hope you like it!

He looked like any other teenage boy, sitting on a bench in Central Park, watching the people pass with their thoughts and things to do. From the outside he didn't like his whole world was caving in, like he could feel his heart tearing, like he knew that nothing would ever be okay again.

He remembered his father's words: to love is to destroy.

He smiled bitterly. Who ever thought that he would agree with Valentine on anything? Then again, hadn't his father been in the same situation? He had also given his heart away to a Fairchild, but with him it hadn't been evil circumstance that had broke his heart, it had been his own evil. Jace wondered idly if he would become like Valentine.

He certainly felt angry enough at the world. But then he thought of Izzy and Alec, and knew that he could never be like Valentine, because there were people who he still cared about, and who still cared about him. He had his family.

Family.

That's all that Clary was to him now. Lying in bed in the institute, he would think of many words that he wished would apply to Clary. Friend, at first. Then girlfriend. Then soul mate.

And most recently, he had been thinking wife.

Sister was not, and never had been one of those words. But now it was his reality.

He leaned his head against the cold iron of the bench, and looked up at the dark December sky. He could see small flakes of snow, feel them falling on his face.

He quickly brushed away a memory of him and Clary playing in the snow just a month earlier, seeing her laughing green eyes gaze up at him and realising that this was it, that she was his forever. How quickly things could change in such short time.

Sister.

How he loathed the word. How he wished he could loathe her, but the only emotion he felt when he saw her was love.

But she was his sister. Fate was so cruel.

He was shaken from his reverie when he felt his phone buzz in his pocket. He took it, and felt his heart constrict for a second when he saw the familiar wallpaper of Clary bent over her sketch pad, biting her lip, her face etched with concentration, her hair loose and wild.

He quickly flicked onto his message, and when seeing it was from Clary hesitated, before clicking on the open button.

Three words, three short words that made him want to both shout with joy and cry hysterically.

He did neither, but instead imagined her saying those three words in his arms, her head pressed against his chest, her words muffled by his shirt.

He imagined her saying those words in some parallel universe where they could be together, where no forces could tear the other away, so great was their love.

"I love you too," he thought to himself, alone with the gently swirling snow.
