I've been waiting to talk about The Shadowhunter's Codex until my copy came in. It is here so let's have a look.
First of all, I ordered the regular edition, pictured above. It is a hardback book in a dust jacket.
Our Twitter friend @Urs_Uriarte posted this picture of her "deluxe" edition.
As you can see above on the bottom right and below, we have some gorgeous images on the front and back inside covers.
Immediately on the title page you see this hilarious interaction between Simon, Clary, and Jace.
Study the handwriting a closely because these three make notes throughout the Codex.
So, if you don't have lot to spend, you really aren't missing much by getting theore "deluxe" edition. Codex is full of interesting information and graphics. I leave you with a few more images. And feel free to tweet us with your copy of the Codex!
EDIT: the images from the front and back covers were mistakenly labeled as drawn by Cassandra Jean. This tidbit has been fixed in the text. The image in the bottom right of the collage is by Charles Vess and the full size image was done by Rebecca Guay. However the Codex does in fact contain images by Cassandra Jean.
