The Last Hours

About The Last Hours

Set roughly a generation after The Infernal Devices, The Last Hours follows Cordelia Carstairs, the daughter of a disgraced Shadowhunter family, as she arrives in London hoping to restore her family's honor by joining a marriage of convenience to her childhood friend James Herondale -- son of Will and Tessa from The Infernal Devices. When a sinister figure called the Lightwarden begins turning ordinary weapons into instruments of a demonic plague, Cordelia, James, and their circle of friends (many of them children of Infernal Devices characters) are drawn into a conspiracy that threatens all of London's Shadowhunters.

Cassandra Clare returns to the Edwardian-era London of The Infernal Devices with a new generation of characters, letting longtime readers watch Will and Tessa's children navigate their own forbidden loves, family legacies, and demonic threats. The trilogy leans into the found-family warmth and tangled romantic entanglements that made Infernal Devices a fan favorite, while adding a mystery-driven central plot about the Lightwarden's true identity and motives.

Three novels tell one complete, continuous story, closing out the era of London Shadowhunters that Infernal Devices began.
