City of Fallen Angels: The Mortal Instruments 4

City of Fallen Angels is the fourth book in Cassandra Clare’s The Mortal Instruments series, and it kicks off a new arc following the events of the Mortal War.

Clary Fray is back in New York, training to become a Shadowhunter and finally able to call Jace her boyfriend. But peace is short-lived. Someone is murdering former members of Valentine’s Circle, stirring tensions between Shadowhunters and Downworlders. Meanwhile, Jace begins to pull away from Clary, haunted by dreams and secrets he won’t share.

At the same time, Simon, now a Daylighter vampire, is grappling with his new identity, strained relationships, and a dangerous offer from a powerful vampire. As darkness creeps back into their lives, Clary and her friends are drawn into a mystery that could ignite another war—and cost them everything they love.
