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.

The Shadow Market is a meeting point for faeries, werewolves, warlocks and vampires. There the Downworlders buy and sell magical objects, make dark bargains, and whisper secrets they do not want the Nephilim to know. Through two centuries, however, there has been a frequent visitor to the Shadow Market from the City of Bones, the very heart of the Shadowhunters. As a Silent Brother, Brother Zachariah is sworn keeper of the laws and lore of the Nephilim. But once he was a Shadowhunter called Jem Carstairs, and his love, then and always, is the warlock Tessa Gray. Follow Brother Zachariah and see, against the backdrop of the Shadow Market’s dark dealings and festive celebrations, Anna Lightwood’s first romance, Matthew Fairchild’s great sin and Tessa Gray plunged into a world war. Valentine Morgenstern buys a soul at the Market and a young Jace Wayland’s soul finds safe harbor. In the Market is hidden a lost heir and a beloved ghost, and no one can save you once you have traded away your heart. Not even Brother Zachariah... Ghosts of the Shadow Market will be co-written with Maureen Johnson, Robin Wasserman, Sarah Rees Brennan and Pulitzer finalist Kelly Link and will initially be available digitally. The first eight stories will be published as e-books from around March 2018 monthly, with the final two available in a print bind-up of all the stories, to be published in 2019.
