A new trilogy, set around 1903, following the next generation of Shadowhunters after TID. More information to come.

Cassandra Clare said about writing more books in the Shadowhunter World:

My plan at the moment is to do five Shadowhunter series, total. I don’t know if I’ll do any series in the Shadowhunter world beyond that. I don’t know why five exactly — maybe because one of my major literary idols has always been Tamora Pierce and she did five series set in Tortall. :) Maybe I think I have five stories to tell in this world. Maybe I’ll get to the end and want to tell more. Maybe not — I have a stockpile of other worlds and stories in my head; I’m writing one of them by writing Magisterium now, but there are many others.
