Really well done. Although Cassandra Clare's writing still has its flaws, she has gotten much better over the years, and so have her stories. I'm enjoying this as much as I did The Infernal Devices, and I think I like the characters (as a whole) even more. I really got attached to the Blackthornes and Emma, and it's nice to see more of a group dynamic in this book - Clare is surprisingly good at writing the scenes where the whole family is together. Seeing familiar faces was also a nice touch, as well as the way the three series are interwoven. 
 It's going to be hard waiting for the paperback for Lord of Shadows!!!
