Jocelyn’s Story (Clary’s mother) was released by the author, Cassandra Clare, as a treat to her readers, celebrating her 10,000 followers on twitter.

The fine print on the text reminds the readers that: [*AN Though this was originally written as part of City of Glass, it was too long, explained too much, and had to be shortened and altered. While it's fun to believe that this is how things were for Jocelyn, this excerpt has to be considered non-canon or alternate universe, so don't be surprised if things in future Shadowhunters books contradict this version of events, or if it contradicts things in City of Glass.]

Jocelyn is telling Clary her story, so you’re Clary listening to it:

“I met your father in school, about the same time you met Simon. Everyone should have a friend like that in their lives. But he wasn’t that friend to me — Luke was. We were always together. In fact, at first, I hated Valentine, because he took Luke away from me.
Valentine was the most popular student at school. He was everything you’d expect of a natural leader — handsome, brilliant, with the sort of charisma that led the younger students to worship him. He was kind enough, but there was something about him even then that I found frightening — he glittered, but with a sort of cold brilliance, like a diamond. And like a diamond, he had a sharp and cutting edge.
When he was seventeen, his father was killed in a raid on a lycanthrope pack. It wasn’t a standard raid — the pack had done nothing to break the Law, but I didn’t find that out until years later. None of did. What we did know was that Valentine returned to school utterly changed. You could see his sharp edges all the time now, the danger in him. And he began to recruit.”
