The Shadowhunters must catch a killer in Edwardian London in this dangerous and romantic sequel to the #1 New York Times bestselling novel Chain of Gold, from New York Times and USA TODAY bestselling author Cassandra Clare. Chain of Iron is a Shadowhunters novel. Cordelia Carstairs seems to have everything she ever wanted. She’s engaged to marry James Herondale, the boy she has loved since childhood. She has a new life in London with her best friend Lucie Herondale and James’s charming companions, the Merry Thieves. She is about to be reunited with her beloved father. And she bears the sword Cortana, a legendary hero’s blade. But the truth is far grimmer. James and Cordelia’s marriage is a lie, arranged to save Cordelia’s reputation. James is in love with the mysterious Grace Blackthorn whose brother, Jesse, died years ago in a terrible accident. Cortana burns Cordelia’s hand when she touches it, while her father has grown bitter and angry. And a serial murderer is targeting the Shadowhunters of London, killing under cover of darkness, then vanishing without a trace. Together with the Merry Thieves, Cordelia, James, and Lucie must follow the trail of the knife-wielding killer through the city’s most dangerous streets. All the while, each is keeping a shocking secret: Lucie, that she plans to raise Jesse from the dead; Cordelia, that she has sworn a dangerous oath of loyalty to a mysterious power; and James, that he is being drawn further each night into the dark web of his grandfather, the arch-demon Belial. And that he himself may be the killer they seek.

An inheritance of shadows. A love in chains. An unconquerable foe. Cordelia Carstairs is a Shadowhunter, a warrior trained since childhood to battle demons. When her father is accused of a terrible crime, she and her brother travel to London in hopes of preventing the family’s ruin. Cordelia’s mother wants to marry her off, but Cordelia is determined to be a hero rather than a bride. Soon Cordelia encounters childhood friends James and Lucie Herondale and is drawn into their world of glittering ballrooms, secret assignations, and supernatural salons, where vampires and warlocks mingle with mermaids and magicians. All the while, she must hide her secret love for James, who is sworn to marry someone else. But Cordelia’s new life is blown apart when a shocking series of demon attacks devastate London. These monsters are nothing like those Shadowhunters have fought before—these demons walk in daylight, strike down the unwary with incurable poison, and seem impossible to kill. London is immediately quarantined. Trapped in the city, Cordelia's friends discover that a dark legacy has gifted them with incredible powers—and forced a brutal choice that will reveal the true cruel price of being a hero.
