About the book

Shadowhunters retreat to Alicante as Clary Fray's brother Sebastian attacks their Institutes, using the Infernal Cup to turn their defenders into soldiers for his army. Clary, Jace and their friends must stop an enemy who knows their families and the divisions within their community. Meanwhile, Jace struggles to control the heavenly fire inside him, a power that complicates both the fight and his relationship with Clary.

Reader notes

The sixth and final Mortal Instruments novel follows several connected viewpoints and assumes familiarity with the earlier books. Bloody battles alternate with romantic entanglements and extended reflection on the characters' shared past. The YA fantasy romance includes non-graphic sex involving teenage characters.

About the author

Cassandra Clare

Cassandra Clare is an American writer of young adult fantasy best known for The Mortal Instruments and its larger network of Shadowhunter stories. Her novels place young protagonists at the threshold of elaborate supernatural societies, then move them through mysteries, factional disputes, family secrets, and unstable alliances. The prose is direct and descriptive, with dialogue carrying much of the character development and romantic tension. City of Bones establishes her characteristic urban method by revealing vampires, werewolves, and demon hunters within contemporary New York, while Clary’s entrance into that hidden order ties discovery to danger and forbidden attraction. Clockwork Angel relocates the same broad world to Victorian London and adopts a more gothic atmosphere, using Tessa Gray’s shape-changing power and search for her brother to organize a conspiracy plot around questions of identity and belonging. In later Mortal Instruments novels, Clare widens the cast and alternates among linked conflicts, allowing supernatural politics, intimate loyalties, and threats to the Shadowhunters’ institutions to develop at the same time.
