The shadowhunter's codex

Since the 13th century, the 'Shadowhunters' Codex' has been the one and only manual for Shadowhunters looking to brush up on their demon languages, learn proper stele use and discover just what exactly a pyxis is. Featured in both 'The Mortal Instruments' and 'The Infernal Devices', this guide is a necessity for any young Nephilim on their journey to becoming a Shadowhunter.
