2With the Mortal Instruments in his possession, Valentine means to unleash havoc on Shadowhunter and Downworlder alike. Despite this, for many in the Clave, fighting alongside werewolves, faeries, warlocks, and vampires would be as terrible as submitting to Valentine. Clary must convince them that working together-aided by her new rune-creation ability-is their only hope for a future! Beautifully illustrated by artist Cassandra Jean, this volume also features an original scene of sudden allies sizing each other up, written exclusively for the graphic novel!
