Once there was a teenage boy named Alexander Lightwood but people called him Alec. He lives in the New York Institute He had three siblings and their names were Isabelle but people called her Izzy, Max and Jace. Jace is Alec, Izzy's and Max's adopted brother. Max died during the war. Alec and Izzy's parents were shadowhunters and were away most of the time and Alec was the responsible one of the three. He dated Magnus Bane during the war against Valentine Morgenstern. Magnus broke up with Alec after Alec went behind Magnus' back and went to see his ex-girlfriend Camille and ask her about Magnus' past.
There also was a girl named Angela. She was born in Los Angeles. Her parents’ names were Tony and Sarah. Her father Tony came from a family of shadowhunters who left the Clave way before Tony was born. His parents told him the truth when he was 18 and he decided that his children would be shadow hunters. Sarah was a mundane. Sarah left Angela and Tony when Angela was three years old. Tony raised Angela to be a great shadow hunter.
The story starts after the war and Alec and Magnus are still apart. Alec started to have visions of a girl that he has never met before and stared to wonder who it was. Alec told his siblings about the dreams and they thought that the girl he keeps seeing could be his soulmate. Angela on the other hand, didn’t tell anyone about the dreams because she felt like it wasn’t anyone’s business.
Alec was sitting in his room with Jace and Izzy when their parents walked into his room. His mom accepted the fact that her oldest son was gay but his father didn't take it very well. His parents were arguing about something when they walked into Alec's room. Robert looked sternly at his wife and said. "I don't understand why you think it's a good idea to let our son marry someone of his own gender."
Maryse put her hands on her hips and said 'I don't know why you can't accept Alec for who he really is. Our son is old enough to make his own decisions and we shouldn’t make his decisions for him."
“You two do realize I'm right here right?” said Alec worried about where this conversation was going.
Maryse and Robert look at the three teens and remembered that they weren't supposed to hear the conversation they were having. They all look at each other for a while in silence.
"Ok, since you guys were talking about Alec and now we want to know why you two were talking about him." said Izzy.
Robert sighs and says "Your mother and I were just talking about a marriage for Alec."
Alec gets off his bed and stares at his parents in shock. He is completely speechless that his own parents would arrange a marriage for him. Alec thought that his parents trusted him. When he finally finds his voice he yells "You're arranging a marriage for me!?"
Maryse starts walking towards Alec to try to explain the situation, when Alec runs past his parents and out the door and into the hallway. Robert yells "Alexander! Alexander wait! Let us explain!"
Alec runs through the institute, with his mind racing with questions. He didn’t understand why his parents didn’t trust him to make his own decisions in life. All he knew was that he couldn’t trust his parents ever again. He didn’t know if Izzy or Jace would agree with their decision and he didn’t care. He was old enough to make his own decisions. He wasn’t going to get married to some girl that he didn’t know, and he wasn’t going to stay in this Institute.
He runs straight to the library and closes the door. He puts a locking rune on the doors. He hurries down the steps of the library to the portal and then does the combination to the portal. Alec stands in front of the portal second guessing his decision to run away but he knew that he didn’t belong here anymore. Alec looks around the library and remembers all the good times he had here.
As he is thinking, he hears footsteps hurrying down the hallway. He looks at the portal and thinks really about the girls he has seen in his visions. Alec knows that once he jumps through the portal to another city or country he cannot come back to this Institute ever again.
“It’s now or never.” Alec says to himself.
He then runs towards the portal and jumps through it. The whole Institute starts to shake and everyone stops walking fast down the hallway and realizes what Alec has done. They run to the library and try to open the doors. When they wouldn't open they realize that Alec had used a locking rune. Jace then uses an unlocking rune to unlock the doors and rush into the library. They all find the portal open and Alec gone.
