One thing Cassandra Clare can do so, so well is making the reader feel happy, so happy you smile so much that your face hurts, and then that smile fades just in a matter of seconds and you're left feeling down. And then straight back up again! 
 HOW?!?! Anyway, Welcome to Shadowhunter Academy felt like I was reading a Shadowhunter novel rather than a novella. It flowed so well, the descriptions were beautiful, the dialogue (like always) was incredible and the plot was just intricate and beautiful and original. Simon Lewis was once a hero, and now he's trying to be another hero... but he knows he cannot return to the one he used to be: one that summoned angels, that slays demons, that saves the world. He knows this. 
 By the Angel, I love Simon Lewis. He's got so many layers to his personality and his background history weaved into this novella and made it feel alive. So many Isabelle and Simon moments (new and old) were put in here, and just in 78 pages, Cassandra Clare makes you FEEL THINGZ. 
 It's official: Just in front of the Mistborn world and Roshar, the Shadow World is my favourite book world of all. The time and effort she has put into this world, the characters, the plots, the timeline and the Easter eggs are BEAUTIFUL. 
 BLOODY AWESOME NOVELLA, BASICALLY!
