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.
