City of Heavenly Fire: The Mortal Instruments 6

City of Heavenly Fire is the epic finale to Cassandra Clare’s The Mortal Instruments series, and it doesn’t hold back.

As Sebastian Morgenstern wages a brutal campaign, turning Shadowhunters into monstrous “Endarkened” using the Infernal Cup, the world teeters on the edge of collapse. The Clave retreats to Idris, but even the demon towers of Alicante can’t guarantee safety. With the Shadowhunter world under siege, Clary, Jace, Simon, Isabelle, and Alec must risk everything—venturing into the demon realm of Edom, a place no human has ever returned from.

This final installment is packed with sacrifice, heartbreak, and redemption, tying together threads from The Infernal Devices and setting the stage for The Dark Artifices. Expect major character arcs, devastating choices, and a conclusion that reshapes the Shadow World forever.
