Chapter one

Clary's alarm clock was beeping. Clary groaned and rolled on her side raising her hand to turn it off. "School..." she thought "I hate school." She clambered out of bed and got changed before rushing down stairs to get breakfast. "Ready for your first day back?" Jocelyn Fray asked her daughter. "I guess it just feels like I've been away for ages when really it everyone else's first day back to." Clary said sighing. "I guess it's bound to feel like that after fighting in a war and then having to go back to school and pretend everything is the same" Jocelyn said giving her daughter a sad smile "You better hurry up you don't want to be late." "Right, bye" Clary said running out the door.

"Clary are you listening to me?" Simon Lewis said frowning at his best friend. They were standing at their lockers in the middle of Goode High School. "Huh, yeah I was just looking for someone" Clary said distractedly. Simon frowned "Rachel doesn't go here anymore." "Oh" Clary said looking dejected "what about..." " Oh Percy still goes here, I'm not really friends with him anymore" Simon said shrugging. "Oh, why not?" Clary said slightly confused, Percy and Simon used to be pretty good friends. Simon shrugged again " Not important, let's get to class."

Clary was sitting in Java Junction, on her own after school, drawing. Simon had to get home quickly so she was on her own today. She was about to get up and head to the institute, where she had training when she heard a familiar voice behind her. " Yeah Chiron convinced Piper and Jason to stop looking." She turned around to find Percy Jackson sitting at a table with a blonde girl with stormy grey eyes. Percy noticed her looking and him and smiled. "Clary? Wow I haven't seen you in ages" He said. "Yeah" Clary said nervously " I was away for the summer holidays." "How's Simon" Percy inquired "You are still friends right?" "Umm..yeah" Clary said an uneasy feeling ran through her body, Percy seemed different, almost more powerful, which was stupid "I have to go I'm meeting my ..boyfriend." This wasn't technically a lie, she was going to meet Jace, just not where or to do what Percy expected.

"So your telling me you think this guy from your high school is a... supernatural being" Jace asked Clary for about the hundredth time. "Not exactly, I'm saying he seemed...weird you know like off, not fully human, the girl he was with seemed even powerful, I think we should check it out" Clary said nervously, she felt weird after her encounter with Percy in Java Junction "And who's Chiron? What were Piper and Jason looking for?, that not exactly something you hear everyday is it?" Jace frowned lost in thought eventfully he said " Ok I'll do it!" "Do what?" Clary said frowning " Jace I'm being serious." "I'll go undercover with you to your school and check out this Percy guy and Isabelle can come too, to bad Alec's on holiday with Magnus this is his kinda thing" Jace said smiling. Clary frowned " Are you sure that'll work?" "Yes, I'll tell Maryse to call the school and enroll us" Clary sighed this would be interesting.
