In this, the first book of the ‘Infernal Devices’ series, sixteen-year-old Tessa Gray crosses the ocean to find her brother. However, arriving in Victorian London, she discovers the terrifying and supernatural amidst the gaslit city streets. Kidnapped and hunted, Tessa soon discovers her own rare ability: to transform into another person. Joining the Shadowhunters, who swear they will help find her brother if she uses her power to help them, Tessa faces an arcane threat which could destroy the world. Similar to her ‘Mortal Instruments’ series, Clare creates a world where romance, intrigue and danger track Tessa’s journey.
