The second instalment of The Infernal Devices follows Tessa and her two dashing Shadowhunter companions, Will and Jem, as they travel throughout Victorian 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.
