"The fourth installment of the graphic novel adaptation of Cassandra Clare's bestselling The Mortal Instruments! Maia and Simon are kidnapped, and Jace knows exactly who took them. It's time to face the terror known as Valentine to stop him from slaughtering the Downworlders and activating the Soul-Sword. All the Shadowhunters gather to join the fight, but when they find themselves hopelessly outnumbered by thousands of demons, the fate of the world...

Clary must convince them that working together--aided by her new rune-creation ability--is their only hope for a future!" --back cover
