Summary: Jace and Clary don't know each other. They are on opposite ends of the Shadowhunter school food chain. The only thing they have in common is this: demon slaying skills. So, when their teacher assigns them to kill one of the most feared Shadowhunters in the world, Clary and Jace must travel around the globe to find him and kill him.

"It's simple," Mrs. Jenkins told the two students. "You two are going to kill Valentine, together."

TWENTY MINUTES EARLIER:

Clary sighed and doodled on her notebook. She had finished her demon hunting quiz twenty minutes ago, while her fellow Shadowhunter friends were still scribbling on their papers and glancing up feverishly at the clock.

Well, they weren't exactly her friends.

Clary Fray wasn't popular. She was a nerd, a geek, a dork. And in this school, no one liked a nerd, or a geek, or a dork. Little did they know that the frizzy red-head was the second best Shadowhunter in her school.

Second only to Jace Wayland.

Jace was popular. His blond hair and tawny eyes got him pretty far, but his talent got him the rest of the way. He could kill demons and downworlders. He knew the name and weak point of almost everything. The only thing he didn't know was Clary's name.

"All right, pencil's down." Mrs. Jenkins stood from her desk and began walking around the hall, collecting test sheets. There were sighs, whispers and shuffling papers. Jace sat, smirking. Clary despised him. He was conceited and a jerk. He didn't care about anyone but himself.

Mrs. Jenkins smiled as she whisked Clary's paper away. "Clarissa, could I borrow you after class?" she asked Clary. Clary nodded, confused. Was she in trouble? But then, why was Mrs. Jenkins smiling at her.

The shrill bell rang, and Clary jumped to her feet. She lingered by her desk and waited for the students to trickle out. Looking over, she saw Jace lingering, similar to her. Suddenly, Mrs. Jenkins called them over.

"Jonathon, Clarissa," she greeted them each in turn. "As you two may know, you are the most talented young Shadowhunters." Jace glanced over at Clary in surprise. He'd seen the girl in the halls, but never had he guessed that she was a good demon slayer. "So, I'm giving you a mission. You are aware of Valentine, yes?"They nodded.

Valentine was the most feared Shadowhunter in history. He killed for fun, and spared no one. "Well, you two are going to find him, and kill him. You will do this instead of your studies. It will be your project."

"Me, work with him?!" Clary was incredulous.

"Me, work with this nerd?" Jace was outraged. Mrs. Jenkins stood from her desk and gathered her papers.

"It's simple. You are going to kill Valentine, together."
