Secrets of Blackthorn Hall [Reading order]
If you want to read SOBH, but don't really know where to start, this post is for you. Cassandra Clare never really added an index to the official SOBH tumblr page, so reading it is a bit messy because you have to go to the archive page and go all the way down. That's a waste of time, so here you have a list of all the chapters of this short novel in publishing order. You just have to click on each link to read it.
