This is set in 2015. I wrote this before The Dark Artifices/The Last Hours/Tales from the Shadowhunter Academy came out, sorry if something is different if you're reading this after they are published. He arrives mysteriously in New York where he is found by the New York Institute Shadowhunters. Except he's been dead for 78 years. (My bios are really bad. Just try the story.) Almost all characters and ideas are Cassandra Clare's. The pictures on the cover are Cassandra Jean's, though the collage was done by me. ~Natalie

What would have happened if Tessa had found a way to make Will immortal and what would happen when they were introduced to the "last" Herondale? Keep reading and find out!

Have you ever wondered what it would be like, if all the characters from The Mortal Instruments, were to read The Infernal Devices? I'm sure you've all heard by now, that Tessa Gray will almost certainly be in 'City of Heavenly Fire'. Well, what if, all the TMI characters, plus Tessa, who by the way, is still alive, read The Infernal Devices? What would some of the reactions be? And when I say, all the characters, I mean all of them. What happens, when all the characters mentioned from all over the series, and more, are all transported to Idaris, to partake in reading? What happens when Magnus, yet again, enters Idaris, but this time...with sparkles!?!? What's Tessa's reaction to all this? Not to mention, (SPOILERS) Jem Carstairs, being a silent brother, and all the infernal Devices characters coming to the future to read. This is gonna be fun! If you haven't read all of The Mortal Instruments and all of The Infernal Devices, by Cassandra Clare, I suggest not reading this. Possible Cursing

This is essentially a rewriting of city of lost souls. Sebastian wants to burn the world down, but before he does that, he needs his sister. He needs her to approve, to love him and clap as the world turns to ashes. When, finally, his sister turns up in his secret dimension-moving apartment, he knows he has a chance. But, Clary loves Jace and sees her brother as a nothing more than a evil half-demon world-burner. To find the love of his sister, Sebastian must change. But, what if it's too late to change, or, worse, what if he can't change?

The Shadowhunters of London get sent into the future. There they meet Magnus, but a more sparkled version, and the modernized Tessa...she happens to be, well different from the Tessa they knew. They also meet The Shadowhunters from New York. As they struggle to get back to their time they discover many things.

IN THE PROCESS OF BEING EDITED "Will and Jem stood side by side as they stared at the world before them, eyes wide in disbelief. Finally, after what felt like an eternity, Will turned his blue gaze to his parabatai. 'Jem, where in God's name are we?' 'I think you're asking the wrong question, Will,' was his friend's only response. 'Perhaps the better question is not where we are, but when.'" - When a portal that Henry tries to make goes wrong, Will and Jem are catapulted through time and space, only to arrive in present day New York. With the assistance of friends old and new in a race to get them back to their own era, the two friends are each faced with a harsh reality: do they like the future they've paved way to, or can they still change it? All of the characters were made by and belong to Cassandra Clare.

His eyes gleamed as he leaned back in his chair. His breath sent a wave of chills down Julia's spine, but it was his words and his confirmation that made her stomach flutter and her heart race. The fandom world is real.
