I do not own the Mortal Instruments, Infernal Devices, or Ashley Arthur series. They belong to Cassandra Clare and Jack Heath.

Chapter 1:

Ashley Arthur was at her fiend Benjamin's house planning their next heist. They were going to break into an old church that had been converted into a house.

"So you know what you have to do?" Ben asked.

"Yes," Ash replied.

"OK, then tell me what the plan is again," Ben said.

"Why?" Ash asked.

"So I can make sure you remember it," Ben explained.

"I have to put on black clothes, and pretend I'm supposed to be there. I go to the library. On the second floor there will be several different cases with valuables in them. I need to find the one with the angel necklace, and get the necklace out. When I finish, I leave and meet up with you at Java Jones. See? Not that hard to remember," Ash replied.

"OK, I was just checking. I wouldn't want you to forget the plan and still think you knew it," Ben replied.

"When have I ever forgotten a plan?" Ash asked, rhetorically.

"How about we go to Java Jones now and get some coffee?" Ben asked, hopefully.

"Can't. I have to get home, or my dad will start to wonder where I am?" Ash said. "But I'll see you Monday."

Ash walked home, thinking about the heist they were going to pull off. It should be pretty easy. All she had to do was pretend to be… what was it they called themselves again? A shadowhunter? That was it. She had to pretend to be a shadowhunter. Not too hard.

"Happy Monday!" Jace declared, walking into the kitchen.

Clary, Simon, Isabelle, Alec, and Magnus were seated around the table. Jace walked over to them and sat down in the chair on Clary's left side.

"I don't see what's so happy about it?" Isabelle said, scowling. "I was supposed to go shopping today and now my plans have been canceled due to the Clave coming."

"It won't kill you if you can't go shopping," Alec pointed out.

"When's the Clave meeting?" Clary asked, taking a sip of her coffee.

"Around 10:00," Jace answered.

"Do any of us have to be there?" Simon asked.

"No, we aren't allowed," Jace sad, a little disgruntled.

"I'm going to be in the library," Clary announced.

In the end everyone else decided to join Clary in the library. It was almost 10:00 when the Clave arrived. Clary and the others were sitting in the library. Clary was drawing next to Jace who was reading. Isabelle and Simon were talking quietly, and occasionally Clary would hear Isabelle giggle. Alec and Magnus had gone off into the stacks, presumably to find a book. A slightly red faced Alec and a grinning Magnus had just returned when the door to the library opened.

A girl of average height walked in. She had brown hair and brown eyes. Honestly, Clary thought she looked like the person that you forgot about a few minutes after you left their company.

"Oh! I didn't realize anybody else was in here," the girl exclaimed. "I'll just go…"

"No, we don't mind if you stay," Clary said. "I'm Clary and this is Jace, Alec, Isabelle, Simon, and Magnus," Clary gestured.

"I'm Ash. Are you sure you guys don't mind if I stay?" Ash asked. "I'm visiting and I've heard about some of the artifacts you guys have here. I was hoping to look at them."

"Of course we don't mind. All the artifacts are on the second floor," Clary said, gesturing to the stairs leading up to the second floor.

"Thanks," Ash replied and made her way to the stairs.
