Everlasting Shadows {A Mctudor AU fanfic}

Her steps were slowing down, Will's voice becoming farther and farther away. A silhouette came walking towards her from the street. She gasped "Will!" Kat immediately put a hand over her mouth. That gait. It was limping as if one of its legs was missing. She took out her seraph blade and that little light was enough for her to make out a demon. She charged at it "ARGHH!!" The demon ducked and swayed around her like he was dancing with her, his opponent. He was whispering under its ghostly breaths, things she couldn't make out. Kat struck it with a powerful swing and it howled, it's skin peeling where the seraph blade met its skin. She smelled rotting flesh, pushing away the will to throw up. Confusingly, the demon was not attempting to attack her whatsoever. Its whispers became more audible. "Carl wants girl" it repeated those words until she couldn't take it anymore. She screamed so loud and it shriveled back out of fear.

"KATHERINE WATCH OUT!!!"

Will.

She took a step to face Will but something hard hit her in the head. Kat fell to the ground at a jarring impact, her skull felt like it was about ready to combust in absolute pain.

SUMMARY:
Kat (Katherine McNamara) has lived her normal life as a Shadowhunter in Brooklyn until one boy; a Shadowhunter changes it all (Will Tudor)

--Twisted dark secrets. Evil Shadowhunters. Many things could put Kat and her friend's life on the line, but who will be at fault?--

BOOK COVER ARTIST: @ajblackthorn

MORE DETAILS: This is an alternate universe with Katherine and Will, instead of doing a fiction story of their life on set or traveling together (like it's been proven on their Social Media's) I decided to make it more interesting, with them in the Shaodwhuter universe.
I hope you enjoy :) And if you don't ship mctudor then take a seat and leave ;)
