I have never visited Cassandra Clare's Shadowhunter world, and I think I have been missing out. This starts like it could easily be read as a standalone. There are many teen characters to get to know and root for- James, Lucie, Cordelia, Matthew, Thomas, and Christopher to name a few. And I suspect the original Shadowhunter books included their parents. I just had a beef glimpse into a detailed world with demons, vampires, warlocks werewolves, and Shadowhunters. I can't wait to get to know it better!
