A prequel to Cassandra Clare's Mortal Instruments series, the second installment of The Infernal Devices follows Tessa and her two dashing Shadowhunter companions, Will and Jem, as they travel throughout England seeking the full truth behind the Magister's sinister plot. Tessa feels herself growing closer to Jem, but Will continues to infuriate her-moody and aloof, she can't tell what he feels for her...or quite what she feels for him.
